Nice puukko.
Some comments on design and proportion:
The blade in the first photo is much thinner than the handle … creating the appearance of an oversize handle.
The sheath on the second photo is oversize for the knife, creating the appearance of either a small knife or a giant sheath.
I'm not a fan of adding too many color stripes and such on a puukko.
The third photo is much better and less "busy".
It takes some careful fitting and inletting to get the handle down to match the blade width, and the same skills to keep the sheath from being oversize. One reason Pukko often have a pocketed sheath with a leather upper collar is that will disguise the difference.
If you don't have it, get a copy of Bo Bergman's book "Knifemaking" it is the best puukko book around. Some copies are listed at crazy prices, but a like searching will find one at a reasonable price.
If you can come to the knife show in Harrisonburg this weekend, drop by my tables and say hello. You can often find that book there, too.
