So I'm looking at the wolverine jig, and for $100 I get a V shaped stop at the end on an adjustable arm. Am I missing something? Seems kinda pricey, I could use some aluminum square and angle and make my own pretty cheap and pretty quick. I've been using a jig similar to what Rowley talks about in his book, basically a big 4x3" adjustable rest, for grinding. I've done okay on my gouges, but I look at the vari-grind jig and think for the $50 it would be a good time saver- but I feel like I could make my own wolverine jig, am I missing something that makes it worth the $100? I'd rather spend the money on tools.
