Thank you all so much for your encouragement, suggestions and good wishes.
Runs-with Scissors, I haven't figured out how to post pictures yet but I'll try to get some pictures up when I get the two projects completed. It might take a bit of time though as I'm juggling family, study, work and these little hobbies so I hope you'll al be patient! However, I am midway through making the BK10 sheath out of merbau (a type of hardwood) and leather. It looks like that project might be completed faster than the Leuku and I'll try a post when it is done with the Leuku following later. Canadian Maple burl is just so beautiful -- you must be really proud of your puukko!
Thank you for the link Esav. Eric Stoskopf has a great idea with recycling the Becker handles. It would cut down on wastage and be a really handy piece of kit. I'll do the same with mine but I might replace the bolts to accommodate a flat-head screw-bolt instead of the existing allen bolts; I would hate to lose an allen key on the field and not have any way of opening the kit.
TLM -- I've never seen these before. That would be quite nice. Do you have a link to this unfinished blade? I'd like to have a look. Thank you.
