Nice small one-piece hollow handled dagger w/ clever sheath.
Before health issues put a stop to it, I was always a big outdoors 'adventurer'. I have been a professional photographer working with several national companies. My passion was nature and wildlife photography. While living in Oregon, I would routinely drive to the coast and to BLM land to record images. As a part of this I became enamored with knives. Upon conducting research I came across the Reeves one-piece line of A2,hollow handle survival blades. To this day, over 20 years later, I have wanted to purchase one. These knives are not cheap to begin with and have increased in value as they are no longer made and prized by collectors. For me, the Schrade schf21 serves as an inexpensive, current production substitute. The schf21 is made of 1060 carbon steel. It has a decent hardness but retains a spring tempure. The blade is 0.187“ (3/16") thick, 0.633" high, and 4.44" long from the guard. The blade can be flexed by hand. The primary bevel is at 24° per side, with a secondary bevel at a whopping 75°. This means the cutting edge of this dagger is almost at a right angle, yikes. Obviously this dagger is meant for something other than food preparation or whittling. Mine came with somewhat of a respectable 'sharpness' given the angle of the edges. The grinds were not quite even. This is sharpened on both edges. You may want to check your local and state laws before carrying it in public. The dagger comes to a wickedly tapered point. The point is usually the weakest part of a dagger and the easiest part to break. This is well mitigated given the spring tempure, edge angle, and toughness of the steel. I would not suggest using it as a throwing knife or dropping it on tile or concrete, but otherwise, it should hold up pretty well. A milled grove runs about half the length of the blade centered between the point and the guard. Some will likely refer to it as a blood groove. Schrade will likely say it is a feature designed to reduce weight. The handle is 0.72" in diameter and has very nice ~30 lines per inch machine diamond checkering. It is a very comfortable grip. The hollow is at just a little over 1/2" diameter and, I think, about 3" long. It could hold a nice compact survival kit (though there are many, many better choices of knives for that role). There is a 17mm (11/16" socket fits with significant wobble) hex shaped cap for the handle. It fits nicely, rotates smoothly and has an O-ring gasket for waterproofing. The cap ends with a bright satin finished window breaker. At the rockosso (sp?) the handle has two beveled flats that aide in retention and for orientation of the knife by feel. These flats extend about 1/3rd of the handle length. Where they join to the blade the flat extend outward to form upper and lower guards at just about an inch in overall height. From the guard to a bit over an inch back toward the butt there is a slight unchecked depression. The front of the blade has a schrade stamp. The back has SCHF21 stamped at the guard. There is a small oval of metal ground out of the back flat positioned a little back of the guard. This oval mates with a spring release clasp on the sheath. There is a small slightly darker smooth ridge on the handle a little before the checkering. It maybe a weld line used to attach the handle to the blade. Or, the knife could just as well have been ground from a single billet of steel. The sheath/scabbard is hard plastic. It allows multiple connection methods. There are two 1 x 1/3" ovals on each side allowing for strap pass-through. There is a two inch spring steel clip which curves back at the end. This clip will allow for attachment by thicker belts. The curve at the clip's bottom will prevent the sheath from accidentally coming off a belt. The curve looks like it may cause damage to a boot if attached by the clip. The clip is attached to the sheath by four star headed screws. When removed the sheath becomes much thinner at under 4/5". The overall thickness is just over one inch while the clip is attached. The sheath is about two inches wide and 5 and 1/3" long. Spring lever mating with the milled oval in the knife handle provides decent retention, it can be turned over and vigorously shaken up and down without loosening. The retention is not absolute and allows the knife to be inserted and drawn, with a bit of a tug, without having to depress the lever. It is a clever design. This dagger is designed for stabbing with a small form factor. There are many, many better knives for cutting. With its small height, shortish length, ans thick edge there are better fighting knives and daggers (cold steel Tai Pan and Peace Keeper series and Gerber Guardian II). The schf21 is one of a relatively small number of double edged dagger. To me it seems mostly to be mostly for collectors and arm-chair commandos. That being stated, I don't doubt that trained military personnel might find it appealing as a compact and concealable offensive stabbing tool. I don't own an Edge Pro or a Sharpmaker and could not be bothered to setup and use the Lansky sharpener. I was able to get the edges hair popping sharp using the groove designed to touch up arrows and fish hooks on a pen/stick portable diamond rod. I really like this dagger. I biggest issue I have with the design is the handle's cap. I would rather it was round and didn't have the glass breaker. A smooth butt would allow more grip styles, greater comfort, and less chance that the knife will snag on clothing. A warning, the retention lever is held in place by a spring tube pin. On mine, the pin walked out of its hole, allowing the lever to be pushed off the sheath by two small springs. Although it was easy enough to put back together, the small parts can easily be lost.
