I'd add that I think some (modern) producers have put a 'maker's mark' on the flat end of the handle, so a venue for marketing flare?
Absolutely.As unsentimental as i like to remain i do think it gives the handle that extra bit of class.
I think anyone lucky enough to have a COTS haft on their axe will be even more pleased if it had a neat maker's mark.
A dedicated forged or fabricated mark is less of a challenge than for stamping metal,as it can be made out of mild,and no worries with ht.
Alternatively there's a fairly long tradition of bending your signature in cursive of of thin wire,heated and pressed into the wood.Heimo Roselli's touch-mark stems from that technique.
Nice to have input from Finland,thanks,Veeteetee.There has always been a right way/a wrong way/and a Finnish way

Their "ponsi"-
Noun[edit]
ponsi
- (botany) anther (pollen-bearing part of the stamen of a flower)
- (politics) motion (parliamentary action to propose something)
- pommel (of sword, knife, axe or such)
- energy, vigour
- weight
- The part of a kantele that holds the varras.
I looked up that video with Russian axes,thanks,guys.
That smaller one by Toporsib is indeed fairly "traditional",one may say.
(T. is a nice,small,humble operation,in Western Siberia(Krasnoyarsk),i used to talk with one of the two brothers that own it,Anton.Much of their design comes from feedback from their customers,much consensus involved).
The second,bigger axe with that lovely knob is by Yuri Pereletov(his two sons more likely).
In spite of their forge being in the heart of what really Is Russia-Kostroma,the center for carvers and wooden architecture,And in spite of the forge's accent on "historical",that knob is totally a derivation of an American idea,(just what you guys are discussing right now).
I've never before seen or heard of a knob in Russia or any other parts of E.Europe.
In the North-west,Karelia,et c. and stemming from there,there's Suomi-inspired "ponsi" swells that russians call "mushroom".
And Glenn brings up a very good point-those cultures much given to a compression eye did not get into swells of any kind.
In some(Bulgaria comes to mind)almost everything is hafted in a compression fit.
Basques and Biscayne region aces are almost all compression,but did try to still have a hook-like swell in spite of that,often in two dimensions only(or as the size of eye permitted).
