Hey guys! I am new to this forum and so far it is cool! I had some questions concerning the BM 42. Here goes:

1. What is the rockwell hardness of the blade? Is the blade through hardened or dual?

2. The handles are made of titanium and cast, are they hardened of left in their natural state?

3. Are the pins made of titanium or steel?

Thanks in advance!

P.S. WrongFriend, it is nice to see you here! I'll e-mail you soon.
 
BA, nice to see you again here!

I'm not sure about the specifics of model 42, only describe my guess from my experience. The blade is made of the same steel as BM's other discontinued models with lower - than - 60 RC. Could be ATS34 was too brittle. Blade pin seems to made of steel, that start to dig my bali's handles a little bit. And the pivot pins is not pins actually but tubes from Chuck' post.

The blade steel is 12C27 Sandivak Stainless Steel and it is around 55-57 on the Rockwell scale. It might be closer to just 57 I am not sure on that.

And I agree I think the pins/tubes are steel.

Hope that helps!

Thanks everyone for the information! For those of you that have the 42, how thick is the blade? Also, does anyone know if the titanium handle is hardened in some way? I'm wondering because titanium in its natural state is not that hard. Especially if it is banging against a steel blade with pin. I havn't had the expierience of fighting with a benchmade or pacific cutlery bali before, but I have used the cheaper ones. They held up, but over the long run, I would have to buy replacements in order to gaurantee safety. Thanks again everyone!
 
My intuition tells me that none of the actual friction bearing parts are Ti. There must be a hardened steel sleeve or bushing in there. Too smooth to be steel on Ti.

Handles appear no more prone to scratching than stainless steel.
 
Steve, washers between handles and blade prevent from scratching. You posted
"Too smooth to be steel on Ti. " and it seems to work not scratching the blade surface at the cost of scratching insides of handles. If cosmetics is the concern, BM realized a very cool rusult by simplest architecture! Only con I feel is, the blade tang pin will dig the handles deeper and quicker than steel handles.
