I bought a Kellum Heidi model not too long ago and it sure is a splindid whittler. After a five gallon bucket of kindling ( I cut thru some knots also ) it would still shave hair off my arm. Resharpening is really fast and the finished edge is fine and polished.
What is an american equivalent to this steel?
 
Basic composition is about C 1.2, Cr 0.7, V 0.1 low alloy mid carbon steel, used for springs etc. often cold drawn.

There was a thread on this before where I asked the same question and got some good answers too. Sorry, can't remeber the answers or where the thread is. Me getting stoopid :(
TLM obviously knows what's what.
It is amazing stuff, to be sure.
 
Well let me ask about the flexability of this steel ..if it's used to make springs...will it take a good amount flexing? If so would the heattreat lessen this attribute? Heidi cuts better than my prized Randall, which has a thinner edge ?????
 
Its often used for knives "puukko" here in Finland. It is sold as cold drawn round bars, 'silver' steel follows from that. Because of the low alloying you have to avoid over heating. Tempering is fairly standard but with C 1.2 you have some play area with carbides.

Couldn't find the standard HT just now, have to look for it.

Thanks for the replies..
What a surprise, I would have thought it would be a more excotic
alloying...sometimes simplest is best..
 
Look my name in review forum and you'll find something. All heat tretment recipies that I've seen are for water quench but the best silver steel puukkos are oil quenched (if my memory serves well). I think that it is quite close to 52100 not A2. A2 is as the name indicates air hardening steel. A2 contains more alloying elements and somewhat less carbon.
 
Thanks Tommi...Good information...Maybe I will consider a differential quenched blade for my next Puukko....
