Question: Is the San Mai III  steel worth the extra $40?
Document: I have put over 100 "trail" miles on this knife in less than two years. Lots of wood splitting and carving poles, stakes, cordage cutting etc. The San Mai III steel is well worth the extra money. It's a laminated steel with the harder stuff in the middle. It has enough belly for field dressing your kill, splitting wood for a fire, or slicing your way through stinging nettles. It's slightly blade heavy with great balance just forward of the handle.
Pass on the other steels with the Cold Steel SRK. The SAN MAI blade is WELL worth the little bit extra for this knife. Nothing else needs to be said about the SRK, it has been around for years and traveled the world and has a well deserved great reputation. The san mai steel only adds to the great knife to make it even better. Wicked sharp, easy to resharpen and durable. At first it may seem expensive then when you consider what you get, you get a bargin
)...and that's only because it has a 8.5 inch cutting edge and a sweet finger choil. They are about equal so far in my opinion although I've used the SRK much more frequently. I love the edge retention of the San Mai III steel. I almost never put a hone to this knife.
This Cold Steel SRK knife is a fine blade, indeed. Made with the San Mai III technique, where a hard carbon steel is encased in their VG-1 stainless steel, makes for a knife able to be super sharp and durable. Out of the box, this knife as exceedingly sharp, made even better when I stropped the edge with leather and jeweler's rouge.
This is &#34;the one.&#34; I own most of the Cold Steel fixed blade line at this point and a few folders as well. This is my daily carry blade. It is, quite possibly, the perfect knife. In fact, I routinely refer to it as Goldilocks. It really is just right. I typically use high carbon only blades and this is the first VG-San Mai III blade I have purchased.
I have a decent knife collection which includes the CS SKR in San Mai III steel as well as a Fallkniven S1. The SRK is very very good. Extremely sharp out of the box. Nice heft, nice grip and nice sheath. Thick blade which makes the knife very sturdy. Did not have to resharpen it yet so can't talk about that. This blade (VG1) comes from Japan as does the one on the S1 (VG10).
What an amazing knife! !Looks great, mean as hell, San Mai III steel, nice'n hefty, super sharp, comfortable  -  what's not to like!If you've seen my review of the Benchmade Nimravus, you won't find this knife on my list of the top 5. That's because I didn't have this knife yet.The first thing I noticed was the heft and thickness of the spear-point blade (a measured .200"). That's a mere .050" away from a quarter inch.
Satin finish blade is superb. San Mai III laminated stainless steel with textured Kraton (rubber-like) handle. Comes with the Secure-Ex sheath. Has lanyard hole in handle. Drop point tip is very sharp as is the blade. Great design. The fixed blade is strong, with a light weight. The sheath actually holds the knife too well. You must use your thumb to break the retention. Great for camping, hunting or self defense.
A hard edge stays sharper but is more easily damaged by activities like hacking through cinder block (a common camping activity). Cold Steel addresses this by taking a very high carbon (hard) piece of steel and sandwiching it between two softer pieces of steel. This allows the knife to keep a very sharp edge while increasing its overall strength and resistance to damage. This is my second Cold Steel San Mai III knife and both have come out of the box razor sharp.
Extremely sharp out of the box. Can easily shred a card board box just for fun. Great for wilderness use or showing off to friends. This knife is my first laminated blade and I'm shockingly surprised at its high quality, even though I was quite skeptical at first. San Mai III steel is quite amazing and leaves a good first impression. Glad I made the purchase.It arrived from amazon in excellent condition and was packaged like they were expecting it to travel through a hurricane.
