Leather Sheath
Leather Sheath
Leather is known for its durability and traditional appeal. When compared to Kydex it is preferred for its silence when bumped against other objects, as well as blade retention.
1095 Carbon Steel
1095 Carbon Steel
An excellent hard use steel, 1095 is a primary choice for camping and larger fixed blade knives for its extreme toughness and ability to hold an edge. Corrosion resistance is very limited with this steel (it will rust) and most blades come with a coating to prevent premature rusting.

Great Knife good value
I received a USGI issue Marine Corps Combat Knife some 43 years ago when I was in the military. Since it was my only fixed blade knife for many years, I used it for deer hunting, camping, building shelters, working in my garage, and hiking. I used it also for a one week survival training course in the military. I once built a 3 person shelter in the Upper Penn of MI with that knife (with some evergreen branches, 550 cord and HD garbage bags) which I used for deer hunting in the winter. The blade is made of carbon steel (parkerized) and it will take a nice edge. The blade can also be used with a flint or fire-starter rod to make decent sparks to start a survival fire. The 7" blade is a little long for general utility purposes. In the USMC we used it as a survival and utility knife. We were also trained to use it for close combat but fortunately I never had to use it for that purpose. Today I keep it in my Survival Bag (Emergency Bag). For the money, its a decent knife if you are looking for a longer blade. I think its a great military-type knife. The sheath is leather, and is the classic old-school style. They also make a newer Kydex type sheath for it.

Comparison with another Marine Combat Knife
This is an excellent knife, as other reviewers have pointed out. This review compares a just-purchased Ontario versus a Camillus I bought from Atlanta Cutlery in the early 1980s. Dimension Camillus Ontario Blade thickness 0.1645" 0.1625" micrometer Hilt thickness 0.0822" 0.0767" micrometer Pommel thickness 0.312" 0.1879" slim bite for the mike. Handle dia. (max) 1 19/64" 1 19/64" caliper and ruler The false edge on the Camillus came unsharpened; the Ontario came with the same concave factory grind as the rest of the blade. (I rounded it off because I want a utility knife not a people-stabber.) The general symmetry and quality of the primary bevel, false edge bevel, blood groove and ricasso are superior on the Ontario. I had to relieve the edges of the Ontario ricasso because it was so right-angle sharp that it hung up entering the sheath. The spine of the Camillus has a mechanically jimped texture; the Ontario is smooth. I don't remember what the leather was like on the Camillus; I sanded it years ago. I sanded the rough edges on my new Ontario and it's now smooth as my Camillus. The leather of the Ontario sheath is thicker than the Camillus sheath, but I don't know what years of wear might have done to the older sheath. The Camillus' sheath rivets only have two tabs on the expansion side; Ontario's have six.The Camillus leg-lace hole is 3/16" dia.; Ontario's is 1/4" dia. The Camillus sheath had 5 stitches per inch while the Ontario sheath has 4 and a fraction. DAMHIKT: If you throw your 1095 RC58 knife you will create fractures that only show up after decades of phosphate rust-removal treatments. You will also bend the hilts.

Former Marine
i own a few of these kabar style knives. I like the feel of the handle and weight. I also like that the blade isnt powder coated.This knife has a retro look. Blade isnt razor sharpe yet it cuts just fine after all it is a combat utility knife. You want to shave get a razor. Great knife and knifecenter has allways come threw with there products and custermer service. Sheath is middle of the road. I order a leather sheath with USMC stamped that fits Ontario usmc combat knife P4.
