Honestly, that thing has blown me away. It is so light and packable but cuts like a dream. Its a bit thin (as saws are) and without a frame support you can bind it up if you aren't watching your angle of entry but once you get into a rhythm it will earn its keep for sure! Now I don't have a lot of experience with similar folding saws but I can tell you this thing WORKS!
I have yet to try carving a Kuksa.. I do have 2 carved from birch both made by a fellow named Alexander Yerks, who posts/sells a lot over on BushcraftUSA..
My entire folder collection minus a few knives here there that live in tool boxes etc.. It also doesn't include a custom TSF Beast I have on order.
