well my mate has a spyderco Manix he says its apperently got the best blade material do you guy have any thoughs anywyas thatt hepps for all your helpp
The Manix is made of S30V, which is a premium blade material. One of my favorites, too.
But which blade material is the best is a matter of opinion. S30V was the "hot new" blade steel, but now ZDP-189 and others have surpassed it. Until those steels become more commonplace, S30V is the easily attainable super (stainless) steel.
But it *is* stainless steel (as is ZDP-189), which has pros and cons. Many tool steels are harder and tougher. In terms of cutting performance and toughness, S30V is definitly not the top steel, or even close. However, many consider it one of the best overall steels because it is also stainless and has very good performance for a stainless steels. The tool steels that vastly outperform S30V are not stainless. However, keep in mind that ZDP-189 is stainless. I see little reason for someone to say S30V is better than ZDP-189, at least for smaller folding knives (versus a chopper).
The Sebenza is S30V (and was formally BG-42). Chris Reeve (maker of the Sebenza) was one of the first to use S30V and helped develop it.
An inexpensive knife that uses S30V is the Spyderco Native ($40), but not all versions use S30V.
Some prefer BG-42, ATS-34, CPM154 (and even 154 CM), and VG-10 to S30V. D2 is a nearly stainless tool steel that is often loved for EDC.
Lots of good choices. The winner depends on what you want in a steel. If you are going to chop wood and do heavy prying, S30V is not the best. It isn't tough enough and you will chip the edge and probably break the tip. A very tough tool steel like A2, or O2 would be better. Even an inexpensive carbon steel like 1095. However, for a pocket knife that is used for cutting, S30V is very hard, holds an edge for a good while, and is stainless (which may or may not matter to you).
