your making some nice stuff, i would suggest you try and lengthen the edge bevel. I have built a lot of knives out of saw blades before building my forge and at first, i had the same edge problems. the grind is too steep so it doesn't take an edge well and also will drag in the leather. Also, a nice polish helps with the dragging problem, actually, the blade gets pinched in the cut as it is just to thick
What critters have antlers over there in Oz? Or is that a roo tusk lol.
