The Blade: The Equestrian has one blade; a locking 3-5/8" long (3-1/8 cutting edge) stainless steel pen blade. It's made of Victorinox' standard stainless steel and is just a hair over 1/16" thick. It's flat ground. Here it is with a Buck Vantage Avid for size comparison...
The blade itself is good; good size and the lock (mentioned above) is great. The problem is the blade steel; it's too soft for ferrier use. It dulls rather easily when cutting horse's hooves, and any of the work in a barn such as cutting heavy lead rope (as in leading the horse to water, not beating the horse with a lead pipe) or opening hay bales will dul it quickly. Carrying a diamond sharpener with you is almost a must with this knife. The blade opens with a nail nick.
The Wood Saw: It's a saw and it cuts wood, as well as other things in the barn. It's 3-1/2" long and 1/16" thick. As a saw should be, it's relatively flexible.
The saw opens via small protrusion on the end of the knife; you have to get your fingernail underneath it to open. Not a big deal, but it's hard to do with gloves on. The saw's teeth are the same as on all other Victorinox knives; very sharp and very functional. they cut on both the push and the pull strokes.
The Combination Tool: This is a conbination of the following tools: medium flathead screwdriver, bottle opener, can opener, and wire stripper. It's 1-1/8" long. A hitch stops it in the halfway position.
It works very well as a can opener and bottles opener, leaving clean cuts. As a flathead screwdriver, it's good for low-tension work because it doesn't lock. for anything else, you'll need a real screwdriver or you'll be busting your knuckles a lot. I've never used the wire stripper on it, so I can't comment on that tool.
The Hoof Pick: Th is is what separates the Equestrian knife from all other SAKs; the hoof pick. It's 1-5/8" long with 5/8" of dedicated "pick". It's just over 1/16" thick and doesn't lock, but it's plenty stout. There's no tapering off toward the tip; it retains its thickness throughout.
In use, the hoof pick does its job; it cleans your horse's hooves without hurting them. It also has dozens of everyday uses, but you'll figure those out for yourself with a little time. It's a nice addition to the knife and what makes it an "equestrian knife".
In all, the Victorinox Equestrian knife is a good deal. You get a lot of useful tools in one package. You'll still need another blade for heavy cutting in the barn or stable, and the lack of an included sheath hurts, but for $27 you're getting a lot of useful tools without weighing you down.
