convexing a hawk blade?

Vaunripped · Jan 29, 2011

the question is if you can do it the same way you convex a knife, as in can you use the sand paper and mouse pad method?

thanks for any and all help and comments

Try a method that was mentioned in the Sharpening/Maintenance forum combined with the mouse pad approach.

Pringles can with bottom cut off and one side pushed flat. Lay or fasten mousepad over curve. Sandpaper/PSA film on top and go for it.

Otherwise, I'm working on some homemade 1/2" Edge Pro convexing stubs.

ok thanks, ill try that, was just looking for ideas, and since i dont have a belt grinder i was looking for a way to do it by hand

the pringles can method only works for a recurve. for a hawk blade you might want something a little larger than a mousepad. i use a belt sander for convexing knives or anything that needs a convex edge put on it. check out post 92 in this thread http://www.bladeforums.com/forums/showthread.php?t=585019&page=5

Yeah, convexing an axe in the same manner you would a knife is no problem - even less so with a hawk as you can easily just pop the head off and not deal with the handle getting in your way. If you're not happy with the profile already on the blade though, definitely use a file to do the re-profiling and save the sandpaper for refining the edge and smoothing out the arc.... otherwise, you're going to be wasting a lot of time and sandpaper!

Refer to this post to see the method in action on a hatchet head I'm restoring for my grandfather :thumbup:

send me an email and i'll shoot you my info. i need to make a new vid of k II cutting the free hanging newspaper since that one is a little dark. i cut down a tree that is 8" across along with 2 smaller ones and it still shaved hair and push cut newspaper.
i have pictures of the tree at my website with k II stuck in the stump.
