*Steel Cutting Note*

*Steel is sold by the foot*(EX: A quantity of 3 is for a single 3 foot bar.) we receive the bars in 4 foot lengths (CPM steels are 3 foot) Please provide cutting instructions in the shopping cart left of the total price in the box "Special instructions for seller". Anything over 3 feet will cost extra for shipping and will be cut. If you do not provide specific cutting instructions and order more then 4 feet, bars will be cut in half. CPM steels will come in uncut 3 foot lengths if full bars are ordered (3,6,9 feet etc.) Example: An order quantity of 8 in 1095 .125"x 2" will result in four 2 foot bars. 7 foot order will have two 2 footers and a 3 footer. Please comment/ contact to change.*

My personal favorite steel so far, excellent edge retention while being super tough. recommended temper is 1000F , which means very hard to burn the edge while grinding! 

Info about CPM M-4 from distributor. 

"CPM M4 is a high vanadium special purpose high-speed steel exhibiting better wear resistance and toughness than M2 or M3 in cold work punches, die inserts and cutting applications, but these reasons are why it is widely used in competition cutting blades.

A brutally tough steel, it bears a fair warning it is hard to work within a hardened and tempered state.

While it may eat up belts grinding it after hardening, its superior edge retention and general toughness make it near impossible to ignore and worth the trouble.

However, if you are used to tough to grind and polish steels, you will be more than ready to try your hand with M4 and will undoubtedly find yourself grinning the first time you test its edge."
