I have a Puma Whitehunter I bought in 1971. I haven't used it in years but recently got it out and sharpened it using the Lansky set at 25 degrees per side. I've been thinking of thinning the edge down to 20 degrees/side but wonder if the blade steel is tough enough for this angle. Can anyone tell me anything about the steel used in this knife? Thanks.

Hi PTN,
The steel is similar to 440A (Different name in Germany, though), with a hardness of about 57-58 HRC.
Take care,
Tobse !
 
I bought a smaller puma in the mid 70's (forgot the name) and sold to a buddy. I foung the edge didn't hold up like my then favourite gerbers(my how times have changed) The edge did roll under heavy use so I would not recommend thinning down the edge or changeing the angle unless it gets just light use.
 
I also have a Puma White Hunter that I consider my favorite deer hunting knife. I have sharpened it with the Spyderco Sharpmaker with 15 degree back bevel and 20 degree primary bevel and have had no problems yet. I cleaned one small buck with it this fall.
There is a supplier in Europe with a great website for puma knives. It can be found at
( http://www.tool-shop.com/knives/puma/index.html )
I also was wondering about the steel type of Puma knives, so I posed the question via e-mail to Stefan Mueller, who I believe is a customer service rep for the above website, and he gave me the following reply:

Kevin,

Sorry, I should have given you this information with the first message.

1.4110 composition:

Carbon: 0,65%
Silicon: 0,40%
Manganese: 0,50%
Chrome: 13,0 - 15,0%
Molybdenum: 0,45 - 0,60%

HRC: 57-59

Kind of a mixture between 425 and 440A, but more similar to 440A.

Best regards,
Stefan Mueller

Thank you all very much for your replies. You have helped me great deal. Perhaps I'll see how the current bevel performs this season, providing I get a deer. Thanks again.
