A SAK is usually always with a riveted design and construction and require no need for adjusting.
Victorinox enhanced the strength and construction when the 111mm liner-locking category knife was introduced in the early 1990s. The first may have been the Dutch Army knife in 1993. Let me know if other information exists.
What I do know for sure is that it is a tank built knife that would take harder use by services. My information mentioned this specifically that it was a category knife that could be used by them. See my Fireman
The Wenger 130mm category is a knife made for harder outdoor use and for special purpose needs.
This category knife is used
and tested by professionals.
I strongly recommend looking closer on the construction on Victorinox and Wenger knives. The construction and mechanism can be interesting and educational to see. The
opening and closing is mechanical and there is no spring assist opening. The spring on a SAK is advanced but it is mechanical.
Time and time again i find articles across the world that confirms all my philosophies and the impressions on the importance of rescue-blades.
It is important for me to continue to underline the need to remember the safety. The key factors in the outdoors are light, knife and fire possibilities.
If you are around moving devices
and mechanical or electrical machinery then you know about the danger of getting stuck or tangled into rope, lines and belts. One swing with a quality blade may save your life.
In the modern
world you must have in mind when you are around in the outdoors that other people may have forgotten to bring a cutting device or a knife. You will therefore have a certain responsibility for the people around you and the situations. People get stuck in places
that can be rather unbelievable with tragic end.
If you have safety in mind you automatically train yourself for situations that may happen. The key to avoid panic is to have an automatically
reaction. This automatically reaction comes from the prepared mind. The unprepared mind may panic and use too much time. Panic is the last thing you want. To prepare must not be considered a weakness that some may say. It is not a weak act to prepare for situations.
It must be considered important and fun!
