Swiza D02

Here is a Swiza knife and it is the D02 model. Swiza is a new Swiss knife Brand that you can find the web page for on the internet for further Company History. Mr. Peter Hug former CEO of The Former Wenger Company is involved so one can already make a good idea about how what is going on. A Swiza knife won the Red Dot Award 2016!

The first I like to do with a New knife is to do an over-all quality check and control on the product. Next I do some small tests to see how it perform and to feel the functionality. This is a Swiss product for sure! It is a fresh and nice design with some extra interesting details. It got a push lock release mechanism to fold the blade in after use. You must use two hands to open the main blade. It got a liner type locking mechanism.

There is something familiar with the blade steel that is a good selection of 440 Stainless with 57 HRC. This is a very well balance for such a type of pocket knife.

 As far as I know it is only Victorinox today that makes a Swiss Army Knife so this is not Swiss Army Knife, it is a Swiss knife and that is good enough because this is a quality knife and comes from Switzerland. It follows the traditions with utility and functions that are so welcome with us that like versatile products.

Everything got polished parts with good precision; maybe the liner-lock should be a bit more precise. I like the soft touch handle scale material and the blue color on this. There are color selections on them.

The main functions: Awl, Phillips driver and the knife blade. It can be opened by left handed as well as right handed.

Well designed awl or reamer type that be used to drill. Thus further you push the bigger the hole will be. It got an interesting cut hole on the awl itself too.

The Phillips driver will work on smaller to larger screws.

It also got well designed tweezers....


It came sharp and ready to be used right out of the package. With this steel quality it is possible to touch it up for greater sharpness. Also take notice on the number on the tang!

Swiza knives carry the Swiss Emblem that in this case is also the push lock release we know from Former Wenger Swiss Army Knives.


By using stanless steel liners you get a sturdy construction


Next little test is to see how the steel, blade design and edge bite in wood. I have this tough piece of ash-wood that should give a good estimation on the blade. It bites in wood with little effort and can remove wood easy. It cut controlled shavings. That the steel bite in wood is important for the quality in my mind.

 “That the steel bites in wood tells something about the design, tempering, edge and quality”

Phillips update

One detail I like extra is that even if that the handle is less than 10 centimeters the length of the Phililps driver function is long. This is important not only to reach hidden screws, it is also important for the controlled hold with the hand. The design of the handle is very comfortable and the Phillips driver is locked secure between the fingers. The length is long enough in my hairy hand 🙂

Phillips screwdriver

I have tested the Phillips a little bit on different cross track screws or Phillips head types. I grabbed a random cross track again to see how the screwdriver performs on a bit harder tasks. Maybe I would go for a tip part Phillips design that is a bit shorter. The length of the tool itself is perfect but a bit shorter tip section is a bit sturdier. It did perform well.

Over-all I give the Swiza D02 5+

Swiza D02 Red

My latest knife is a Red Swiza D02. The red actually got orange in it and that is Swiss Red to me with a smile. Same quality construction!


03.07.2016 Ergonomics update

Ergonomics and design

One of my favorite subjects is ergonomics because this is the continuation of comfort, safety and design. The Swiza knives are very well designed and it is a completely new and fresh introduction with Swiss Knives. The curve on the handle is so that when you use the knife blade the curve will secure the handle from slipping forward or backwards. The design of the handle scales secures the handle from twisting. The soft touch material that is slip-resistant will enhance the safety further. It is also a comfortable material that prevents uncomfortable use. The same thing is with the awl when you use that function.

The handle curve design with ergonomics works very well for the Phillips screwdriver that I have pictured for you on this Swiza page. It is possible to hold the handle in different grips when using it. It is also very comfortable for the hand with the controlled grip for safe use when you must apply some force and push-controlled motion.  

Ergonomics is my mind is also very much related for preventing accidental slip. I will explain and what I mean is the mind memory for safe. When the handle is secure in the hand using the knife blade you have a comfortable and safe grip. The ergonomics is also very much related to the last cut. When you have used the blade in a cut-motion you restart for the next cut. The mind will automatically be ready for the next cut. If the handle would be uncomfortable your mind will have that factor influencing. That is or could be a negative factor for some cutting tasks. I give the Swiza ergonomics 6 of 6.

“ A locking blade is very much related to ergonomics as well”

technical update

“The Swiza knives got a slip joint mechanism. The individual functions are operated by the spring or springs. It is typical Swiss that one spring may operate more than two functions at the same time. This is typical Swiss and it is a well-tested system with a very long history. The more modern knives from Switzerland are often accompanied with a locking mechanism to prevent accidental closing. This locking type mechanism does many times have a small play motion against the lock. This does usually never ever influence the safety. The locking mechanism is an evolution of the comfortable and safe use of the knives. Accidental closing with a slip joint happens from time to time and the lock is made exactly to prevent this.  It is also typical with knives made in Switzerland that there are notches and designs on the tangs of the functions. This is many times made to be a kind of locking mechanism for the function itself. A notch on the tang towards a counter notch in the spring will make it a bit more difficult for the function to fold in. These notches influence the safety, comfort and ergonomics positively. The liner for the lock with the blade is a better design that secures a far better lock against accidental closing. That you can fold the blade in by pressing the emblem gives the best safety”


Scale attaching update


How the handle scales are attached to the side-liners are another typical Swiss design. In history you will find a huge selection of different methods for attaching hidden rivets side plates or handle scales. The Swiza knife is a riveted design that is typical for the famous SAKs. The correct term for a Swiza knife is not a Swiss Army Knife because it is only Victorinox today that can make an original SAK. I would not hesitate to have the Swiza Brand and knife in the popular terms SAK anyway. If I should mention some more about the handle scales then I would bring out two design features with the hidden rivet handle scales. If I should mention one Company in the history that made SAKs then it would be the former Wenger Company. They had many different methods for attaching the handle scales with hidden rivets. By using both press fit over the bushing head for the rivet and by using opening with design features that could be attached on the side liners. Today it is normal to use two component plastic handle scales that maybe injection molded for great precision. It is possible to make handle scales that consist of harder and softer materials. The inner part may be a bit harder so it will have a stronger and more durable attachment for either bushings or openings in the side liners. There is something familiar with Swiza knives and many of the details remind me very much about Wenger knives. It is an innovative design with many familiar factors. Mr Peter Hug is very much involved in Swiza knives so I would expect former Wenger expertise to be involved in the design and production. By using local cutlery knowledge from Delemont and Jura you will get quality.


Polished parts update


There was some computer trouble so the little note about the polished parts is gone. It is typical that Swiss knives have polished parts and functions. By using polished springs, functions and parts you can get better precision, ergonomics and functionality. It is easier to clean a polished surface and it is easier to see the problem if something should prevent functionality. Polished springs and functions will secure a better durability and functionality. The comfort is better and the ergonomics as well. Polished surfaces are better against corrosion. The spring tension influences the opening and closing of a function. If a surface is rough it will or may get corrosion and dirt in the mechanism that is more difficult to distinguish and see. Also more difficult to remove and if corrosion happen it is very difficult to remove from such a surface.

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! :)

03.01 | 15:08

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

03.01 | 15:04

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
