I have tried a few pieces of Olive from Jerusalem and here in Spain, in addition to the cracking issue, I noted that the wood seems to warp easier when going from a dry environment to a moist environment. I no longer use Olive wood for that reason.

Working on finishing this. I don't know what to call it. Sword? Waki? The blade is 16.5" long, it's about 22" overall. I cut this out months ago, sat on it for a while, rough ground it, sat on it for a while, sent it out to Bos for heat treat. It's 3V. Really happy with how it's turning out. It's been both a catalyst and a measure of how my freehand grinding has improved over the last 6 months. 6 months ago I wouldn't even have considered not hand sanding. Now if only my design ability could catch up 
I don't know what I was thinking about the handle. But I think I can work around it.

Kuraki, call it whatever you want, but I like it 
I think it would look good with a paracord wrap/braid handle.

It's hollow ground so it's just where it came out based on the radius.
Finished this late last night. It's going to be a gift for a friend. First real knife that's going to someone other than myself. It's a little neck knife forged from Cruforge V. 600 grit satin finish with black and red g10 scales and nickel silver pins. I also made a little kydex sheath so he can actually wear it around his neck when fishing.

Great looking blade there Kuraki!
I've found that you can push hollow grinds surprisingly high with a relatively small wheel, it just takes some finesse and is really easy to screw up. Id say ~1.5x the typical height is doable without excessive blending.
Of course then you have guys like Gil Hibben who will do a 2" high hollow grind on an 8" wheel
Oh I tried the Gil Hibben grinding, after a few scrapped blades I went back to what works for me. I still probably screw up 1/4 of the blades I really try to push the grind on. They cut very well when it works out thoughLots of people can do things I cannot, or do not want to risk trying
I'd like to do some of those as well sometime. I have an idea for a grinder with a 48" contact wheel I'd like to put together eventually.

Do you have a good idea on how to put rubber on it? I have the resources to make a wheel of any size but there's no way I'm going to pay what contact rubber and others want to put rubber on it.
I have some castable urethane that's shore 70 that would be my last resort, since making a mold to do a one off, then turning/truing everything while not knowing if it will even work is not something I want to devote time to.
I spent some time looking for self vulcanizing rubber that came in tape form or something but that was a bust.

I've had a few ideas, but I'll have to do some testing on smaller scale to figure out what actually works. Felt contact wheels have been used for a long time as well, could be another potential option.
That is another of my ideas. I've got a splitter and a skiving machine around from doing harness work, which would definitely help.
When I eventually have the time I'll try making a couple smaller contact wheels, and see what works. A 10 or even 14" is a lot less time and materials than a 36 or 48

Bruce Bump showed me a knife with about an 1.5" hollow grind made on a 3" wheel. But of course he is Bruce Bump.
If I recall right, Jerry Fisk will do his flat grinds probably 90% of the way as a hollow grind. On a 4" wheel.
