I must not be able to keep my dremel straight, I brake blades like crazy. I use a cold chiesel and a small slegde or 24 oz. ball peen hammer. If you don't have a cutting surface like an anvil, small pcs. of train rail, or even the rail plate that is spiked down between tie and rail work good and they have holes in them if you want to nail them down to a stump or the like. I use a file and or a bench grinder to shape. Cut em alittle big. I like using band saw blades, you can get a lot of points out of them. sometimes I even cut them at an angle and leave the teeth on as one edge of the blade, got that idea from my 7 yr, old
. I've not shot one yet, but they look grusome. I haven't hunted large game w/ these either, I mostly make small game points. Check you local hunting laws and if all's good, I'd believe if sharp, they'd take about anything down if hit in the vitals. Good luck and better yet, have fun.
