These are fine grained custom cutlery steels that have very good edge retention properties and are stronger and more corrosion resistant than cheaper common steels. <BR/><BR/>DLC refers to Diamond Like Carbon and is a super thin coating that is incredibly hard, scratch resistant and corrosion resistant. It's pretty much the gold standard right now in coating technology as far as I can see.<BR/><BR/>58-60 Rockwell is generally the hardness range that you want to see in knife steels. In theory anyway, 58 Rockwell is a good target for these type of steels where you want good hardness for edge retention but at the lower value you are trading off a little hardness for greater toughness, a handy quality in a prying tool.<BR/><BR/>After a vacuum hardening heat treat and temper cycle all of my stuff is cryogenically aged in liquid nitrogen and then retempered. This further refines the grain structure and improves edge retention, toughness and hardness.Peter Atwoodhttps://www.blogger.com/profile/16246505554623368895noreply@blogger.comtag:blogger.com,1999:blog-30128634.post-70254490695941747222008-10-25T18:07:00.000-04:002008-10-25T18:07:00.000-04:00Is there a glossary for CPM and Rockwell and DLC s...Is there a glossary for CPM and Rockwell and DLC somewhere?<BR/><BR/>A newbiew question I realize..but while y'all wait for the lottery drawing what else do you have to do? ;)<BR/>bdsUnknownhttps://www.blogger.com/profile/10398053761201317870noreply@blogger.comtag:blogger.com,1999:blog-30128634.post-36224775850461725152008-10-25T16:20:00.000-04:002008-10-25T16:20:00.000-04:00Thank you. :)No, these are CPM 154 at 58 Rockwell ...Thank you. :)<BR/><BR/>No, these are CPM 154 at 58 Rockwell with DLC coating.Peter Atwoodhttps://www.blogger.com/profile/16246505554623368895noreply@blogger.comtag:blogger.com,1999:blog-30128634.post-37543531831451318512008-10-25T16:17:00.000-04:002008-10-25T16:17:00.000-04:00Nice work.

These properties are just the opposite of the, soft, weak and sticky boogers that I've experienced so far.<BR/><BR/>I hope I get to pick one of those boogers.<BR/><BR/>Sorry, I couldn't resist saying that as I've been with my three year old most of the day.Unknownhttps://www.blogger.com/profile/09446356752666199573noreply@blogger.comtag:blogger.com,1999:blog-30128634.post-33154623321415074702008-10-25T14:35:00.000-04:002008-10-25T14:35:00.000-04:00hopefully I'll get lucky tonight : phopefully I'll get lucky tonight : pMatthttps://www.blogger.com/profile/17141521902729111195noreply@blogger.comtag:blogger.com,1999:blog-30128634.post-2803765271064771222008-10-25T12:38:00.001-04:002008-10-25T12:38:00.001-04:00holy, cow, these are beautifulholy, cow, these are beautifulStultifera Navishttps://www.blogger.com/profile/16665006339052535484noreply@blogger.comtag:blogger.com,1999:blog-30128634.post-59894700437220427642008-10-25T12:38:00.000-04:002008-10-25T12:38:00.000-04:00WOW!l Those are great Peter!WOW!l Those are great Peter!DBhttps://www.blogger.com/profile/16458080007931966065noreply@blogger.comtag:blogger.com,1999:blog-30128634.post-60514611868059303742008-10-25T12:24:00.000-04:002008-10-25T12:24:00.000-04:00Very nice Peter!Very nice Peter!Heathhttps://www.blogger.com/profile/10672275561841433259noreply@blogger.com
