Review: The single best fixed blade under $100: Ontario RAT-3 - The Ontario Knife Company Randall’s Adventure Training 3, or the OKC RAT-3 is the best bang for your buck fixed blade in the survival and tool knife market. Micarta handles, 1095 carbon steel, full tang, and MITUSA! This is one of the most utilitarian and practical fixed blades on the market. Pleasantly comfortable in hand, not oversized so you can carry it most places, tough as hell, and pretty easy to get a good edge on. If you can destroy this knife, kudos. The plastic sheath leaves some desire (the nylon is even worse IMO) but did come with a tek-lok adapter when I purchased mine (may not anymore). It’s the perfect size knife for scout carry (the eyelets are the perfect width for a standard duty belt and some 550 cord) or thrown in a go bag. Buy with confidence. Pictured is mine after almost a decade of use and abuse on Active Duty in the US Army, 2 deployments, and multiple trips to Atropia.
Review: Great knife - I have multiple esee 3s as well as the Rat 3 and I have to say I prefer the Rat 3. I like the Rat 3 scales better compared to the Esee 3 as it feels better against my skin when I carry it IWB. I also like the coating on this knife better compared to the Esee as the coating on the Esee sometimes cause more friction due to it being a much thicker coating when passing through material. I actually strip the coating off my Esee knives just because it annoys me in that regard. The Rat 3 sheath is usable but I would recommend ditching it and purchase the polymer Esee 3 sheath as it will fit the Rat 3 perfectly or a kydex sheath. That way you get a ton more carry options and can carry on the belt, IWB, or attach to something. I haven't noticed much of a difference in the heat treat between the Esee or the Rat 3. The Esee is definitely slightly harder steel and will have slightly better edge retention but it's not enough difference to make a difference. Factory edge sucks and needs to be sharpened but I put my own edge on every knife so that doesn't bother me. It's a great knife that will serve anyone well. My only gripe is these are expensive now. I remember purchasing mine a few years ago for far less. But everything is expensive now I guess.

## Questions & Answers

**Q: The description claims in comes with a nylon sheath. Is this nylon fabric or hard plastic? Does it also come with a teklok?**
A: It's nylon fabric with a plastic sheath inside to protect the nylon.

**Q: What steel is it .**
A: Listed as 1095 carbon steel

**Q: Is this a full tang knife?**
A: Yea it is.

**Q: Why is it saying this-blade material: 1095 carbon steel when it is not true?**
A: I don't know exactly how to answer your question. I checked other places (bladehq, ebay, etc.) and get mixed answers. Most say 1095 and some say 1075. Not sure which is correct. Either way, I really like mine and don't think there is a huge difference either way. I do recommend this knife. Hope this helps in some small way.

### ⭐⭐⭐⭐⭐ Best EDC Fixed Blade Knife
*by A***7 on April 22, 2023*

It’s small enough to carry on your belt without scaring non-knife people in public. The steel sharpens easily and maintains an edge well. It’s perfect for detailed carving work. Handle will absorb sweat and oil over time and turn a darker shade, but who really cares. It functions. The sheath could be better but it functions to protect the knife and keep it from coming out. Worth the money and with care will last a lifetime.
