Re-profiling

Modifications and re-profiling + more

If there is one thing about SAKs that are open for impressive areas then it is modifications. There are plenty of people that can do the most incredible and innovative things with them.

If you experience a broken blade on a knife then it is fully possible to re-profile the remains of the blade into a new design. The tip part is the science and how this is done sometimes need a professional sharpener with equipment for it.  I touch this subject again because this can be done on Wenger or Victorinox knives or any other for that matter. You can bring new life to a knife without sending it for repair and it is possible to do yourself. It is fun and gives further knowledge on knives.

If you experience bent functions then it depends on how much it is out of shape and you should not bend it back. If it just a small thing then just let it be. If it much out of place and you must bend for it to close into the body then it is a different matter. No matter what it will weaken the steel to some degree. It depends on how hard you will use it.

If you experience a broken phillips/pozi screwdriver then it is difficult to re-profile it to a new phillips/pozi because it usually will never be as strong and it must/may be smaller. I am careful saying it cannot be done because I have been surprised so many times on what people can do. It is also possible to make a new or different function on it. It will not come and haunt you if you experiment. The same problem may happen on the flat screwdrivers and the steel will not become the same. This is probably because of the tempering and steel process. Let me know! It would need someone with knowledge on it.

If you experience the functionality is not there because of damage or other problems then it should be sent for repair.

When a blade has been broken and repaired it is always a re-profiling even if one make the same shape. On the picture to the right you see a clip point blade on an older Victorinox that i repaired because the tip was broken. Tried to make it similar to the original. It is not rare that you can find knives with broken blades. This is usually always from abuse.

It is fully possible to re-profile broken blades. On this 84mm SAK I had to do this because a good part of the tip was gone. The key when you re-profile is to make sure the tip come below the liner on handle when closed. It is not so fun to have an exposed tip above the line. There is still some work to be done with the edge on this but the functionality is restored and it is sharp. If you use grinding wheels to remove most of the metal when you change the design then remember to avoid heat.

Here you see an old and worn alox model with a re-profiled shape. This I did because a good part of the tip sections was broken on the pruner blade. I still have to do some small work on the edge but it is sharp and functional.

On sakhome.com you can find pages about the steel, how it works and sharpening information.  Some Swiss Army Knives have seen some harder use and therefore the edge may have damages on it. Some damages on the edge could be deep and it would mean removing much metal to get above the damage there. This is a factor worth dwelling upon before choosing the best method or solution. It could be necessary to live with some small nicks in the edge.

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.
