Ontario Knife Company

Randall's Adventure Training has been designing, marketing, and selling survival and military-style knives since their first survival courses in the Amazon Jungle of Peru. One of their first designs was the RTAK which was built by Newt Livesay's Wicked Knife Company before Ontario Knife Company produced the design. ESEE also produced and sold the RAT skinning/survival knife made by John Greco and the RAT Laser Strike knife made by TOPS (ESEE has since re-introduced the Laser Strike as an ESEE knife). Randall's Adventure Training also designed the following knives for Ontario Knife Company: RTAK II, TAK, RAT-7, RAT-5, RAT-3, Model 1 folder and the Model 2 folder. 

The Ontario RAT Model 1 from Randall's Adventure Training is a folding EDC knife that can withstand hard use and abuse associated with tactical or survival tasks. For the money, there might not be a better knife on that market that can match the performance of the RAT Model 1. It features an ergonomic handle with smooth action and rock-solid lockup. The four-position pocket clip allows the user to customize their carry method to their liking. We absolutely love the off-set blade from the handle, which creates a unique look we rarely see in a knife and distinguishes it from all the rest. Whether you need to add a new knife to your EDC rotation (or you think it would make a great fit for a survivalist, serviceman or woman, or a true friend), rest assured you're making the right choice when you go with an Ontario RAT Model 1.

Ontario Knife Company is proud to introduce one of their all-time best selling folding knives, now reissued as assisted openers with their proprietary Tactical Assisted Opening (T.A.O.) technology and G10 handles. This knife has been a long time in the making since the original model was introduced in 2007. The RAT-1 is one of those knives every knife collector should have in their collection, at least at one point. The production quality for the money is absolutely second to none and these knives are built extremely solidly so you can use them for even the toughest tasks. Now, after almost seven years, Ontario has engineered this folding knife for those who prefer an assisted opening blade. They've also improved upon the design by using real G10 for the handles instead of FRN for a better grip under extreme conditions and added a locking mechanism for safety.

RAT 1-A Review
▪︎ This is my EDC, for all purposes. I think its one of the best sub-$100 locking folding knives out there. Blade steel is top-notch, and holds an edge through cardboard, wood, plastics and fabrics. I use it at work and on the property constantly. The assisted opening is a great help for one-handed use while working with my hands. I just wish the handle was a bit thicker with rounded edges

Nothing I don't like
I very rarely buy anything imported but, I watched one of your videos about ten Knives everyone should have and I decided to add a Rat1 to my collection. So I decided on the Rat1A with G-10 scales. The grip and feel are excellent and the assist is strong, no flaws and excellent finish. I hate that I like it this much.

A lot of knife for the money
Purchased to enter my rotation of EDC knives and to complete my RAT collection. This is a large knife but that’s what I wanted. Weight and balance are perfect for me, and the G10 scales are very nice. My only complaint is that out of the box new, it is extremely stiff and does not open easily. In fact, I initially needed to use both thumbs. I am still breaking it in and won’t carry it until it opens with more ease. I am talking VERY difficult to open, though it is getting easier as I work the spring. The soreness of my right thumb tells me that I will remember breaking this one in for a while. If you’re expecting immediate ease of opening, as in similar to a Kershaw Blur, be warned. Otherwise, I am very happy with this knife. For the $$, this blade can’t be beat.
