My favorite (after practicing on the others, they'll all be like this from now on)
the one cut as I'll re-cut the others because I prefer it more than any ... I like this in both looks and tactics more than the fancy bird head snake head stuff- this cut is IMHO tactically superior to the others (IMHO). (But the others look fancier) The sides could be shaped to more point, but I really really like this, and will adjust my other 2 to be of this design also.
It's sharper, opens the hook for easier grabbing, and, it's sharper, and it's less weapons-looking, and it's sharper .. like a razor's edge.
On this particular one with the hickory's heartwood, the edge is something you could almost use to shave.
Darn digital auto camera can't do what my old 35 mm manual cameras in the shed could. ... but the closeup would be incredible if I could turn off autofocus.
My across the street neighbor's husband agrees ... this is sharper, more grab than a sharp point inside the curve ... and it's sharper lol
The other two I'll either modify to be like this, or just keep them as spares until I modify them to be like this, or loan them to any elderly people at my church, though the oldest, a 93 year old lady (one of 2 twins) doesn't use one yet and still mows her own yard so ...
NOW I can go to the City Council meeting and the County Commissioners meetings at the Courthouse

This was simplest of all, sharp diagonal cut with saw, flat file, 220 grit, 320 grit, then 600 grit sandpaper, mineral oil (or baby oil if you prefer the smell) and wax with furniture polish or even a clear shoe polish wax if desired.
Cost, about $30.00 for the cane raw stock hickory heart wood from Canemasters. Not as fancy as their $350.00 cane with the cuts/grips/gatorback ribs, snake/bird eyes etc ... but I prefer it actually.
