Hey folks!
At a certain stage of life, every knifemaker should invent something )) To satisfy the ego, an original design or construction of a folding knife works best. I decided not to break from tradition or disappoint expectations and developed a design for a folding knife specifically for knife enthusiasts in the UK. Throughout the process, I aimed to create a full-sized folding knife that also complied with all the strictest requirements of English law.
I don't consider this design revolutionary, but I tried to make my modest contribution to the creation of a legal everyday carry folding knife. Of course, I'm far from the first in this niche—dozens of knifemakers before me have designed more or less successful knives that were meant to comply with the law. I carefully studied their experiences, their mistakes, and all the pros and cons of their technical solutions. Most of these solutions were related to extending the ricasso, or attempting to interpret the law regulating the length of the cutting edge. Forums in the UK were full of debates about where the length of the cutting edge should be measured from. I found that attempting to interpret the law and methods of measuring the cutting edge were extremely weak and unconvincing arguments when questions of knife legality arose. Any technical solution based solely on interpretations, personal evaluative judgments, and faith in luck is, from a legal perspective, very unstable ground. Therefore, I chose not to engage in these questionable and risky games and instead pursued a completely lawful path.
The full length of the blades of my knives, from the tip of the edge to the liners, does not exceed 76mm. Instead of engaging in questionable practices by elongating the ricasso, I extended the liners. The liners in my knife design are elongated by 25-35mm and visually create the illusion of a longer blade. Thanks to the extended liners and optical illusion, there's a feeling that the blade length is not 76 mm but 110-112 mm. Although, of course, that's not the case.This visual effect is achieved by the liners mimicking the shape, texture, and color of the blade. Of course, significantly protruding liners, with a thickness of 1.5-2mm, could deform during everyday use and carrying, so I found a solution. All liners are made of stainless steel with a carbon content of 0,35-0,40% and are hardened to a hardness of 45-50 HRC. Naturally, this complicates and lengthens the knife-making process, but the advantages outweigh it: 1. Protruding liners do not deform even under heavy stress. 2. A knife with hardened liners is practically indestructible. 3. Such a knife can be assembled and disassembled for customization an almost infinite number of times.
I wanted to create the most reliable, rigid, and user-safe design. That's why I chose to forgo the classic slipjoint and opted for its French version, the non-locking «cran force», developed in the 1820s. When you make a classic slipjoint powerful, the knife transforms into a guillotine, posing a danger to the owner's fingers. The French version of the slipjoint doesn't have this drawback.
During the summer, I submitted all the documentation to the UK Intellectual Property Office. They conducted a check for analogues and similar design solutions, and in September, the IPO officially registered three versions of the design.
I made test samples for the IPO in several versions: classic traditional knives assembled with rivets, featuring carbon steel blades and handles made of natural materials. Additionally, there are more modern versions assembled with screws, featuring composite scales and stainless steel blades. The aim was to offer a variety of models to suit different tastes.
I won't list the sizes and weights—these are custom handmade knives, and none of them are alike.
P.S. When there's time, I'll shoot a demonstration video with explanations.
P.P.S. Some blades bear the stamp "Dionisio Zapatero handmade" – that's my first officially registered brand. It's my Hispanized name, which I use for Spanish navajas and Mediterranean knives. Recently, I registered a second brand in the UK - Denis Cherevichnik.
Cheers,
Denis
