White Nomad Posted March 8, 2021 Share Posted March 8, 2021 As the title suggests, I need advice on how to grind the bevel into a recurve style blade. Any tips or tricks? Link to comment Share on other sites More sharing options...
ThomasPowers Posted March 8, 2021 Share Posted March 8, 2021 What kind of grinder do you have? A belt grinder with a fairly small contact wheel can be used 90 deg to the edge to follow the curve around. Link to comment Share on other sites More sharing options...
Irondragon Forge ClayWorks Posted March 9, 2021 Share Posted March 9, 2021 If you don't have a belt grinder, a 4 1/2 or 3 inch angle grinder will do it. Just have to go slow and be very careful of the rotation of the wheel so it doesn't grab the edge of the blade ( which is firmly held in a vise).

White Nomad Posted March 9, 2021 Author Share Posted March 9, 2021 Thanks for the advice. I use a Rhiobi Bench sander grinder combo, and I've been using the top wheel the get the curve ground down. Link to comment Share on other sites More sharing options...

If you have a rotating vise it will make it easier and firmly locking your elbows to your side and using your hips to move the angle grinder instead of your arms will make the grinds more consistent. Angle grinders are the only powered grinding tools I currently own. I stopped using the large angle grinder and switched to a 4 1/2in grinder and use smaller wheels whenever possible.

anvil Posted March 9, 2021 Share Posted March 9, 2021 A half round file works really well. Link to comment Share on other sites More sharing options...
JPH Posted March 13, 2021 Share Posted March 13, 2021 Hello: If you are referrig to a blade like he one below I just finished today.. I used a 14" dia serrated wheel on my frankengrinder running at approx 7200 fpm.. Just go slow and work the curve and recurve..Takes a little bit or practice but not all that troublesome once you get the "feel".. JPH Link to comment Share on other sites More sharing options...

White Nomad Posted March 16, 2021 Author Share Posted March 16, 2021 No, not a blade like that, I mean instead of the blade being flat or curve away from you before the tip, the blade bends inwards towards you before the tip, I'll upload a pic when I get home and if I remember. I ended up using a really short sen knife and files and just creating the bevel like that, and then used a curved sharpening stone and ceramic to sharpen.

ThomasPowers Posted March 16, 2021 Share Posted March 16, 2021 Kukri, falcata or bolo type of blades is what they are referring to I believe. Link to comment Share on other sites More sharing options...
Buzzkill Posted March 17, 2021 Share Posted March 17, 2021 I recently made a few karambits and ended up using a 2 inch wheel on the belt grinder, slow speed, and a steady hand to sharpen them. To grind the bevels I used a 6 inch wheel. There is definitely a learning curve, and it is harder IMO to get a good flat bevel because you have to rotate the blade to try to keep the spot being ground in line with the belt travel as you grind. I'd recommend trying a mild steel blank first to get the technique down before moving to a blade you want to keep or sell. Link to comment Share on other sites More sharing options...
White Nomad Posted May 6, 2021 Author Share Posted May 6, 2021 It's been a while since I've looked at this thread, but for anyone wondering, I've found that using a sen knife has made it very easy to get the bevel formed. Link to comment Share on other sites More sharing options...
