This knife is what it is--a very good backup knife. It isn't a utility knife. It isn't a hunting knife. It isn't a throwing knife. Rather, it IS a very well made knife, whose sole purpose is to defend your life in an emergency. It's meant to be an easily carried and concealed backup to a handgun or larger knife--or both. I've had no problems with "rattling tips" or any other such nonsense. I like it and I carry it.

I bought one of these for my son who went to Iraq and he liked it so I picked up one for myself. Very sharp. Good quality. My only complaint is that the tip will rattle in the sheath, so I put some cotton in the bottom and that took care of it.

Okay this is a review of my Gerber Guardian purchased in 1983. Original black handle shiney blade. To write this review I walked less then 15' and picked up my knife. What I'm saying there is 27 years after buying it I knew exactally where it is and can lay hand on it in seconds. The blade is designed by R.W. Loveless. The blade is made out of a high carbon very hard steel. It has a dimond shape cross section for making a blood channel. I used it once to put down a deer that had been hit on the road. One poke and there was blood squirting. The wounded deer was forever out of pain in about 10 seconds. Granted I have the anatomical knowledge to use a tool like the Gerber to that affect... don't expect a careless poke to do anything other then make something very angry with you. It was my main packaging knife when I was doing military service. The stiff blade was excellent at cutting tape.... after cutting I'd draw the edge back down the tape to stick it down real good. It is NOT weighted for throwing. I can throw it and did so when I was a silly young soldier. Take the advice of an ol-phart and don't throw it.

Early on I dropped the knife on its point while doing latrine duty. The tile floor curled back about 1/16 of the tip and I reshaped it with a diamond file. It is now robust enough that I used it as a can opener in college... poking it down at the rim and working my way around. It will also turn the frame screws on my eye glasses now. The round point makes it a decent deer skinning knife. The stiff blade will pry into a joint when breaking up a carcass for butchering. The handle is well shaped with the butt nesting against the heel of your palm. I suspect during self-defense it would be left all the way inside an attacker.

I ALSO have an old Gerber boot knife from the early 1980's and the quality is night and day different. The older one used a carbon steel and a very graceful taper from a 1/4" thick base. It was a rather high quality knife for a line-production offering. This knife is .125": about 1/2 as thick. The old one had a well made leather thumb-break sheath; this one has, well a functional plastic one that is a bit over complex for a shank.
I use my terms here carefully. This is (IMO only) just a shank; it's NOT a particularly well made or for that matter strong knife. It certainly will do what it's intended for: last-ditch "better than nothing" surprise......but it really is not up to their older quality.
I also had noted that there are two model numbers and it MAY be possible that for ten dollars more there may be some worthwhile differences; but that's an unknown for me at this time.
The bevel angle is a bit too high for my taste and since we are dealing with a thinner blade, I (personally) would clean that edge us just a bit. The point is likely to chip if stuck into something ridged but the utilitarian handle makes for a very rapid movement; again "it's a shank". My thinking on this is somewhat simple. When a blade is coated with some no reflective surfacing, it is more difficult to clean so as to remove micro-organisms & therefore not designed to eat with, etc. A blade surface that's clean, smooth, naked steel (that can be sterilized or at least made substantially clean) - allows the wider rage of tool use.
A guy I used to know used to say "you can't be disillusioned unless you have illusions in the 1st place". - Therefore my 3 stars: I was expecting better.

This is a good knife for general use. I would not rely on this for heavy duty work but, it would be very sufficient for light use.

This is a great little "hide-anywhere" dagger. The clip is designed to fit snugly over the lip of a boot, and it does so. I wear it with Bates 9" boots, and forget that it's there.
However, it is no good out of the box. The knife rattles in the sheath, really loudly. I fixed this by stuffing a small piece of a cotton cleansing pad down to the tip. That's done the trick. The adaptable tension sheath system works pretty well, once you get the hang of it, but you can't operate it with just your hands.

Pros: Good construction, affordable, good quality, American-made, light-weight, comfortable, easily sharpened, good grip, good balance
Cons: Thick sheath that is difficult to use and can scratch leather boots, dull blade out of box

I collect knives as a hobby. I'm not a serious collector and do it as a simple enjoyment. When selecting knives, I always try to pick ones that are of good quality, and can be used in a work environment, or per their product descriptions, without incurring damage. I was searching for a good, double-edged boot knife to add to my collection, and ran across the Gerber Guardian. So far, I have been very pleased with the knife. It is American made with a double-edged blade and locking sheath. The edges were not very sharp, but the steel is easily sharpened and it did not take me very long to hone them. The knife is very light-weight, and feels good in the hand. The handle is comfortable and easy to hold, giving me a grip that feels confident and secure. The knife is well-balanced, and would be a good throwing knife for short distances and soft targets. Other reviewers have expressed frustration with the tip bending or breaking when throwing it, but so long as you use a soft target, like thin cardboard, then you shouldn't have any problems. The sheath is my only complaint. It is a little too thick to wear concealed in a work boot. I tried it just for kicks, but there was not enough room for both my leg and the knife in the boot. It works with my ropers though. The clip is stainless steel with a somewhat abrasive edge, and it marked both of my pairs of leather boots, which didn't make me too happy. Won't be wearing it in the boot anymore now.
