The OSS (Office of Strategic Services) was the wartime intelligence agency formed during World War II, and is the predecessor to our modern-day CIA.
This knife was named for that intelligence agency. It's Cold Steel's lower-end sub-hilt fighter, the OSS, model 39LSSC. The higher-end version of this would be the Black Bear Classic. The Black Bear Classic and OSS are double-edged knives, but there's a single-edged version of the OSS, called the OSI. The OSS costs around $60 in stores, but you can find them on sale for around $40 (the rumor is that Cold Steel is discontinuing this model). The OSS is made in Taiwan.

The Handle: The OSS has a one-piece handle, made of black Kraton. The handle is 5-1/8" long and 7/8" thick at its thickest part. The sub-hilts extend 3/4" from the handle, and there's 1" of space between the sub-hilt and the guard. This is just enough to get a bare finger inside (I'm a size XL glove) but is uncomfortable with gloved hands.

It's a 3/4 tang knife, and has a lined lanyard hole in the butt. The lanyard hole is a bit small, but will accomodate a strand of gutted 550 cord.

The sides of the handle are textured with a checkered pattern (see the photo above), while the front and back have ridges along their entire lengths.

The butt has no texturing, and is angled more in the back. (See the third photo for this.) The knife has a nice feel, and the balance is right on the main guard.

In a hammer grip, the knife is comfortable. I'd prefer not to have the guard on top, and this can be cut off with an Exacto knife. Other than that, it's comfortable and really locks in your hand due to the sub-hilt design.

In an icepick grip, it's even more comfortable. You can use it with or without your thumb resting on the butt (my prefernce).

The Blade: The OSS' blade is made of Japanese AUS-8A at 57-58 on the Rockwell scale, athough older ones were available in both 420 sub-zero treatent and Carbon V steel. The blade is 8-1/4" long with two 7-5/8" edges. The blade is 3/16" thick and both edges are hollow ground. Both edges -the front and back - came razor sharp right out of the box.
The left side of the blade is lasered as follows:

And the right side tang...

The blade has a high satin polish, and has a very pointy tip.

I haven't used the blade much except for cutting test papers, so I can't comment on its edge retention or ease of resharpening. I can say, though, that it will slice paper readily and pierce with no effort. Both sides are razor sharp, and cutting with the back edge is as easy as using the main edge.
 
The Sheath: The OSS comes with a black Secure-Ex sheath. Secure-Ex is Cold Steel's brand of thermoplastic, and it's rugged enough for heavy use. It measures 10-1/8" long and 3-1/4" wide at its widest, and is 1" thick. There are two slots per side for webbing, as well as five holes per side and two holes on the bottom for lashing. All of the holes are grommeted. Attached to the plastic sheath is a black nylon belt hanger, which is removable entirely, or can be placed on either the left or right-hand side.

(Note that in my photos, the nylon belt attachment is situated for left-hand belt carry; I'm a lefty.)

It's held on with two Phillips-head screws, which go through to stainless steel bolts.

The knife goes into the sheath one way only, as the molding had to be made to hold the knife tightly.

The nylon belt loop is fastened in the back with both Velcro and a button snap, and this enables the user to remove the entire knife and sheath without undoing their belt.

Counting the nylon belt loop, the sheath is 13-3/4" long. The nylon attachment also has a snap closure for an extra bit of security. The sheath retains the knife just fine, even upside-down, and I found it to be a bit too tight. On a belt, it really took some effort to get the knife out. I remedied this by using and Exacto knife and sandpaper on the nubs inside the sheath.

The sheath is nice, and having the option of removing or moving the belt loop up or down the sheath is a nice idea. The sheath can be mounted in any position, and handle-down (upside down) will still retain the knife with no rattle.

In all, the OSS is an ideal combat knife. I would prefer the single-edged version (the OSI) for utility tasks, but for a dedicated combat knife, the OSS is great. It will slice and pierce with ease, and stays in the hand with enough security and comfort to make it a very nice choice.
 
A question for you--the only similar model to this that I've handled was a Boar Hunter prototype, and the guard/subhilt were soft and gave really easily. Is that the case with one? I was hoping it was something that would get ironed out in production and they'd find a way to stiffen it up, but I think I might have just been optimistic. :o

The Boar Hunter and OSI (single-edged version of the OSS) that I handled were the same as the OSS; the sub-hilt was soft rubber (Kraton) and bent with finger pressure, but it always sprung back to where it was with no damage.
