I have talked and discussed some on the use of two components on the EvolutionGrip and the RangerGrip handles here on my webpage. This was first introduced on the 85mm in 2007 as a continuing of the Evolution. This features the Evolution with a better safety for the ergonomics and design. It continues the Wenger versatile development.

In 2007 the New Ranger adapted the Evolution system on the new large 130mm Ranger knives. In 2009 this also received the Grip inlays made of a rubber material. This material can take hard extensive use in the outdoors. The process used making these handles are advanced and continues the safety and comfort for a larger knife.

The rubber material can take a strong grip and friction between the hand and two component materials. I am surprised on how well the rim of the rubber is intact because of the transition there.

It can take saltwater well and I can see no damage caused by the sun and saltwater. I recommend rinsing after use in salty environments.

Inlay update

On a knife used for cleaning fish and for use on foods then the hygiene is important. This is a part I have talked and discussed some before. I have used this knife as a safety knife and a knife to clean fish with. A rubber material can absorb substances more easy than a normal harder plastic materials. It can absorb some smell from fish but it fades away after cleaning and time.  I cleaned with some soap and then rinsed very well. The rubber material does help for safety because it is less slippery.

The Evolution is made for safety and to prevent a slip by itself and the Grip is just a further development of this. It is also helpful in cold weather and for use with gloves. For a safety knife the Grip inlays are very well and good. For hygiene purposes the best is the normal solid plastic Evolution handles.



Rivited design and construction update

Riveted design and construction quality

I would like to talk some more about the riveted design and construction used on Swiss Army Knives. Without a doubt I do like the use of other assembly designs used on products in the world. It is a helpful feature to be able to turn a pivot screw or similar designs. It is so that the Saks usually got the riveted design that can only be adjusted by a professional or a modder. It is so that in all of the cases the riveted assembly is strong enough for the uses it was intended for.

Actually this design may be better than a pivot or different turning assembly types.  I was amazed by the Victorinox 111mm Services Range or the liner-locking type knives. There is not damage to the rivets or pins, the construction is rock solid. If there is damage there you would feel it pretty easy. Victorinox did like we know increase the rivet/pin diameter on the 111mm Services Range and designed a construction that is very good.

After more personal tests on the Wenger Ranger knives I can once again tell that the riveted design is without any negative factors. Wenger did not change the diameter of the pins much but instead use a different material.

One of the factors that I find very interesting is the engineering and product development used on the Wenger Brand knives; it is super modern and made with precision. The construction itself is very important for the forces that are distributed in it during use.  A Sak is very advanced and it is not strange that so many people are interested in how it works and functions.  I can only imagine all the work needed to complete the design of a new category of knives but it is easy to see that the core philosophies and the basic constructions always or usually always follow the new product. It is here that the traditions and knowledge from the beginning until today explains why this works best on a SAK. The knife may be super modern but it is also the result of all the history.


I have continued to use the New Ranger knives for my personal interest and tests. One of the key factors I had in mind was how the main blade and functions would take some force and cutting tasks. I was interested in learning more about how the springs, locking mechanism, rivets/pins and wear would influence the product after time. The most important factor is how it is after some time. I have mentioned around on my Ranger pages about the different factors I have noticed on them. So far I cannot find any negative things to say. Basically there is no change on any parts that would be negative.

 The main blade on the knives is slim and I had in mind the length as well before I tested it. The main blade is rather long, slim and used on a modified liner-locking slip joint mechanism. One would expect that some complications could happen. After rather hard cutting is different wood types and mostly spruce the blade is not bent and there is no sideways play. The main blade also feels very solid when force is applied against a surface with the edge.  By doing so it is obvious that there will be forces working on the pins, slip-joint spring and construction. There is no change after use on the New Ranger knife. It is very solid and the only small play is against the locking mechanism but this was how it came new.

On the New Ranger knives by Wenger you can feel some play against the lock; some got no play and others some more. This is normal and it is because of the lock and that it is designed to prevent accidental closing only and that it is a different construction + the spring design. There are some modifications done on the new Victorinox and Wenger merged products.  There would never be any philosophy other than preventing accidental closing anyhow with such locking mechanism and philosophy. Usually every modification and change is becasue of the constant product development and Victorinox is also much known for this.

I have not used any dates on when I started the personal tests on the New ranger knives but is some years now from time to time.

My research on all the different Victorinox and Wenger Swiss Army Knives on any category, is that the riveted design last and last with good result always.

The biggest advantage with a screw assembly would be the cleaning factor.  

It is important to have in mind that a locking blade knife is not made so people should forget correct use. The best philosophy is that it should be used with the mindset that it is just a slip-joint. By doing so one would prevent a negative surprise if you should use a normal SAK. In the history of the knives the philosophy of safe use is always there. If you take a look around my New Ranger pages and the different under-pages then you can read some more about this and see my philosophy on them. Check out my pages on safety knives as well if you get the time.

It is not easy to explain always with the safety on knives and the products.  


Screw assembly vs riveted design:

I do not want to write and say that one may be better than the other. My impression on any SAK is that it works well enough and the cleaning is not  a problem for a person that cares about his knife.

One very important factor with a screw assembly type is the correct distribution. By this i mean that there would or could be damage on the mechanism and springs if it is overturned or to loose. It would or could produce new problems for peoples use. It would be more difficult thus more functions it got. For the main person or user the normal design used by Wenger and Victorinox works very well. Screw assembly has been used by Wenger on the Eka collaboration for example.



I have seen some other knives that is not Wenger and Victorinox with screw assembly that has a tendency to get loose from use even with lock-tite. It is very strange.

maintenance update

Proper maintenance and use

On the pictures you can see a Wenger New Ranger knife that i have used or had with me on and off for 3 years or so. It is not easy to see that this knife and functions have been soaked in saltwater and fish. I have had it with me in my kayak and in a boat. This knife and the functions I am extra confident that I know pretty much all the quality. It’s been sharpened many times and I have cut all kinds of materials. Take a tour on my New Ranger pages. What I would like to mention is if you have regular cleaning and oil then there will be little or no corrosion at all. The Wenger knives got a selection of stainless steel that is very good. This does not mean people should forget maintenance and sharpening + some oil from time to time. Proper maintenance includes cleaning of dirt, saltwater and objects in the mechanism. Proper sharpening is important for the safety because a sharp knife is a safe knife. A decent edge also add to the impression other people get when they see it or use it. Oil will make the functionality and performance the best. I will have to clean this soon because I can see some dirt that I will remove. This knife and functions I have used much at home as well.

Good luck!

Lifetime update

Proper maintenance and lifetime


With SAKs you read about a life time guarantee on the products and this is very true. SAKs can last a lifetime without any doubt. This depends on a few factors; please take the time to study SAKhome.com for information about the products and functionality as well. Ok! Proper maintenance and use is the key for products that can last a lifetime. This also depends on what use and in what environment. It depends on how hard you use it. I have used SAKs for 10 years, 6 years, 4 and 1 year. I have never had a knife fail or any function break. If damage on the knife or functions it has always been because I have tested too hard to learn and develop knowledge or I have used it too hard. Never any breakage or failure. The Swiss products got a very high quality and I have heard and seen knives used for many decades and are still in working order.

With high quality one must not forget proper maintenance, sharpening and oil for the best functionality, quality and safety. These are the keys for the lifetime product. A guarantee is usually as I see it against defects or any production factors that could happen with the product. This means you got a lifetime guarantee against defects. With SAKs my impression is that average use with proper maintenance will secure a product that could last a lifetime.

It is a completely different thing with Swiss Army knives compared to electronic devices today. A knife can last for a lifetime. This is true! Electronic devices/ functions on SAKs do not have a lifetime guarantee or warranty.


 I have seen Wenger and Victorinox products that are 40 years old and are used for so long. The blades have been sharpened so much that it is just a small piece left of the blade that just as well could be turned into an awl. I have seen knives that the functions cannot be opened. After cleaning, oil and sharpening all the functions are working again and the mechanism/ springs talks again. I have seen knives that are 100 years old and are still in working order.

A knife for a bit hard use will for sure get worn more than usual and different environments will influence the products.

everything i know update

The best Swiss Army Knife that i have or ever seen is the RangerGrip 79.821.X, the knife shown here in this article or page.

Maybe I have a few SAKs that are in the same top notch rank but I am more and more convinced that this 130mm Wenger is the best developed Swiss Army Knife ever made. This knife is probably or represents everything I know about knives vs a product.



The main blade and all the functions on this RangerGrip knife is excellent. The main blade is balanced in the dimension, edge, design, one hand opening, locking mechanism, comfort, safety, quality, durability, edge holding abilities and flexibility. There are some serious flexing abilities and the blade is balanced towards the length of the handle. Please take the time to read my New Ranger pages for further information.

The 120mm continued after the New Ranger. They had Patent and not pat pend. I say pat pend first then patent next. But! Wenger did many variations! :)

The old Ranger 120mm is from 1991, on my 1993 it is pat pend I have seen it on 1991 too and Swissbuck as well! Wenger can be a minefield because of variations

It is a superb question. Wenger used different stamps, some because of european laws. Usually the quality and steel is the same. Which is first? Not sure.

Hi! Sorry for late answer. I have seen many variations with Wenger, please send pic to trondsak@sakhome.com
