Looking for a faster way to get perfectly even bevels when grinding your blades? This file guide will enable you to precision-file both sides of the blade dead-even, using files or your grinder. The benefits are blade bevels starting perfectly even, and stick tang shoulders being dead square and even for perfect bolster fit. The Carbide File Guide is solid stainless steel, and will not rust when dunked in water during grinding as you keep the blade cool. Metal dust will not stick to this non-magnetic steel. The face is protected by two carbide strips, which only diamond or other exceptionally hard tools will scratch. These are 78 HRC and very hard but: ceramic belts can and will damage carbide. This tool is for use with hand tools, or normal aluminum oxide belts if using a grinder. The carbides are 3.9mm thick and can be replaced if required. The carbide strips are recessed slightly down into the stainless steel for added protection. This way the strips will not be knocked off, or be under pressure when clamping a blade in the file guide. This also ensures there is less pressure on the carbide strip when clamping in a blade as they back onto a shoulder of steel. Features & Specs: 3.9 mm thick carbides screwed on, HRC 78 Carbides are adjustable sideways to open or close the gap if your blade is not 100% parallel with the jaws. Non-magnetic, steel dust will not stick to it Stainless, will not rust All screws are recessed into the body for easy access on flat platen Accepts up to 2.75" wide blades, up to 1.18" thick blades and guards Guide pins are hardened steel for sturdy construction and less chance of jamming Long pins for taking thick guard stock or even squaring up handle blocks and other materials Polished face for really smooth, flat carbide surfaces Screw holes with flat bottom so the carbide strips can be adjusted sideways, should your blade not be 100% parallel sided Designed and prototyped in Australia by Bjorn of Nordic Edge: As a hobby knife maker, I struggled with getting a really good blade-to-guard fit up. Like so many other makers I tried one of the file guides that were available at the time, but got frustrated with how the carbides popped off when really cranking down on it. The idea itself was good, I just thought we could come up with a better version. After a lot of work and prototyping, we came up with the Nordic Edge file guide. This is the first file guide in the world with screw-on carbides that cannot come off. We made it using stainless steel that will not rust, as well as being non-magnetic so steel dust won't stick to it as you grind. We think this is a good version of a file guide and you can now grind matching plunge lines, as well as get those really crisp blade to guard fit-ups with less hassle. * knife blank in photos is not included
