  1. RD Ready Detachment Knife 5 Star Review

    Posted by on 30th Sep 2014

    Received what I feel is an outstanding knife. Fit and finish is top quality. The knife for the money cannot be matched. I wish I had a knife like this when serving my tour in South VietNam.
    Now, where is the signature series? I want one. PS: I'm also looking at the Ranger Falcon Hunting Knife.

  2. Another Beautiful Knife from Ontario Knives 5 Star Review

    Posted by on 12th Apr 2013

    I've purchased several different fixed-blade knives the past couple of years, but I've found that overall, the Ontario knives are the best value for the money. Sure, you may find a more expensive knife from different manufacturers, but you won't a better knife for the money.

  3. You'll never fing a more solid knife in this size or price range! 5 Star Review

    Posted by on 18th Oct 2011

    I have owned lots of knives over the years, from cheap flea market stuff to high end $250 and up blades. The Ranger series from Ontario are the best knife series in my opinion for the combat/utility and survival knife class. The RD class..(RD4,6,7 and 9) are all 1/4 inch thick blades with heavy duty textured powder coated finishes that are VERY tough!. The RD 4 is the strongest 4.5 inch knife I have ever seen. Because of its thickness and heft, it does the work of, and can easily replace your current5-6 inch knife, no problem. It is very sturdy, and because of the very durable steel used, 5160, it holds an edge for a LONG time, even after some really heavy use. I use my RD 4 when backpacking, hiking and camping. I wouldn't trade this knife for something twice its size and twice its price! Out of the whole ranger series, Id say most people will find the RD 4 the most practical and useful for everyday application. At $72...Its a STEAL!
