If 154CM I will in all likelihood pass, if it happens to be CPM-154 then I would be much more likely to purchase one.
Yep. But Jerry bought "tons and tons" of 154CM, not CPM-154. So I wouldn't hold out much hope for knives made of the latter.
What is the difference between the two (2) steels? (Sorry, rookie metallurgist here <img src="/ubbthreads/images/graemlins/paperbag.gif" alt="" />)
154CM is an improved 440C, it is relatively large grained with large carbides. The large carbides can rip out of the edge and form micro serrations. CPM is the same steel but powdered first, making it much more finely grained. CPM steels tend to be significant improvements over the 'parent' steel.
A great example is D2. Most D2 can be brittle once it reaches a certain stress loading, it also will be effected by water etc in what is being cut, reducing its edge retention. CPM D2 is stronger and better able to sustain stress before failure, it is also less influenced by water etc.
At least this is my understanding.
