FWIW, I've had several of the Kestrel "standard" size of different bends and i did'nt like using them. I don't like the double edge styles, the blade is too wide to turn easily, for me, there's not much steel thickness left as they taper to the point, and the second edge can be a little more dangerous.
Also, if you make your own, you can make an additional bend at the blade to handle area that angles the blade away from you a few degrees and at least to me, is more comfortable to use.
