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.

Ontario Rat versatile and economical
I work in the field and constantly reaching for my knife, I have a few options but when I know I will be needing to use one all day I pick the Rat.I know it will take care of anything I need it to.It functions well, holds a decent edge, easy to sharpen. I will even let someone use it, and not fear them damaging it.

Not ambidextrous opener and not recommended
I have a RAT 2 and bought the assisted opening RAT 1 because the 2 was just a bit small and, being a southpaw, the left thumb stud cutout on the RAT 2 was a bit too shallow for me. Thinking a bigger, assisted opening, knife would allow my left thumb to flick it open more easily….boy was I wrong! The left stud cutout on the RAT 1 is still too shallow ( probably due to locking spring tab) and the detent is so strong that there is no way a normal person can release the blade with their left thumb. Further, the sharp conical steps on the thumb studs don’t help. I have figured out how to “pinch and push” both thumb studs with my thumb and pointer finger, but it’s not ideal. It’s a shame that I really don’t recommend this knife because everything else about it is great. I’d recommend comparatively priced SOG brand assisted openers over the Ontario brand option.

Why...?
I need to take this thing apart and make it a regular Rat. And I confess to buying it just for a curiosity since any and ever Rat 1 or 2 has always been super easy to flip open. But the assisted open on this thing is TOUGH to get open. I've been absent mindedly flipping it open and closed while watching TV to "break it in" and I can't tell if it's getting any better or not. I love the G10 instead of the usual nylon but I think this will be a better knife if it can be "de-assisted".
