I had to look Marcin Tomaszewski up: he has several links on BladeForum regarding his work. Knifesmithing/making is his hobby.

Many years ago, I bought this puukko on BladeForums from a Russian maker. His modern puukko as he called it, 440C and G10, was very inexpensive. The maker went by the name MrZorg and lived in Moscow, he's not been online in years, I hope the war didn't catch up to him.
I'm a sucker for orange and needed a puukko for my collection.

Still awaiting the Pelotonen M95 (shows as pre-order status; it's the duotone model) here. I found a video from Joe X on Youtube where he broke an M95 on the third swat on a cast iron pipe. He hasn't reviewed the Morkret yet. Note to Joe X, one doesn't swat iron pipes or stab VW windshields with puukko. They're made for utility work at camp, dressing game, slicing meat and veggies, a little bush crafting whilst one is outside watching the Northern Lights and thinking Life is Good!

Nice, modern looking knife UTSig. In the interim, I spotted a nice little Helle Tollekniv on sale and scooped it up.

Nice knife UTsig! Im also a sucker for orange. A rhombic modern puukko would be a quick impulse buy.

As a side note, puukko.org is restocked with all colors (some new) of their Hackman “butterfly” folding puukko.
