Triple Eight Professional has a variety of small performance knives that are great for everyday use. Their knives feature a Patent Pending T8P Spinner Action opening system, which is one of the most unique, safe, and functional systems that I have had the opportunity to work with. The knife I was able to work with was the Rhino Knife, which is designed as a performance knife for the hunter and outdoorsman. The knife incorporates elements that are suited for bass fishing, so naturally we had to see how it would work for the average bass angler.



  • T8P Spinner Action: Triple Eight Professional has designed their own Patent Pending opening system for the knives they offer, including the Rhino Knife. The system spins the two handles of the knife 360 degrees around an axle that opens to reveal the knife blade inside. There is a bolt that slides into place to keep the knife both opened and closed. The opening system design is similar to a butterfly knife, however you cannot swing the knife open with one motion, and the handles split in a different orientation.
  • Blade: The blade of the knife is a fine blade that is composed of heat treated AUS8 Stainless Steel, and it incorporates a gut hook built into the back of the blade that works incredibly well as a line cutter. This is very useful for quickly cutting fishing line or cord, and is one of the best features of the knife due to its simplicity and ease of use.
  • Handle: The handle of the Rhino is composed of black 420 Stainless Steel, which makes the knife look very sleek, but it lacks any tactile grip. There is a hole located at the back of the knife which allows for use of a lanyard or key ring attachment.
  • Clip: The pocket clip on the knife is composed of 420 Stainless Steel and features the company name and logo. The metal clip is very sturdy and allows for a solid hold when clipped to your pocket. You will not have to worry about losing this knife.
  • Limited Lifetime Warranty: The Rhino Knife has a limited lifetime warranty that states, “if you are not happy with your Triple Eight Professional product, we’ll repair or replace if for the life of the product. This warranty does not cover damage caused by abuse to the knife (possibly caused by small children, rabid dogs, or someone’s mother-in-law), neglect, or failure to read instructions due to not being able to find your reading glasses.” Basically Triple Eight Professional offers one of the best warranties I have seen to date on their knives, and who could fault them for not covering damage by rabid dogs?
  • Dimensions:  Open Length: 4.25’’, Closed Length: 3.0”, Blade Length: 1.25”, Weight: 2.0 oz.  

Actual Testing/Use

It was instantly obvious that the compact Rhino Knife was suited for fishing when I was using it to rig up my rods. The knife is user-friendly and it is great to grab when you have one hand busy holding a knot. The design of the knife is awesome, and the action opening system is a great concept. I enjoy seeing the attention to detail especially in a small knife, as many companies overlook the quality that can be offered in a small tool.

Opening the knife is very simple, and it all revolves around the T8P axle. All you have to do is snap open the top half of the handle and rotate it around the axle until you are able to snap the bolt into the other side of the handle. In the process the blade opens and locks into place. The Rhino can open and close one handed, but it is easier to open it with both hands. I would say the single best feature of the knife is the gut hook which I use as a line cutter. It allows you to hook the line and cut it in one motion which is very nice when you are out on the water.

One negative aspect of the knife was the fact that it did not include a rubber or other type of grip built into the handle. The knives offered by Triple Eight Professional are already great quality, however if they offered one with a rubber grip, I feel that fishermen and outdoorsmen would be even more inclined to carry this knife. In addition, the blade of the knife was dull on arrival and required sharpening. I would assume that this is just a random occurrence because the quality of the knife seems to be very high.

Lack of a grip material on the handle


The Rhino is a solid knife that is loaded with features from Triple Eight Professional. They have obviously paid a lot of attention to detail when it comes to creating these small yet effective knives. In a general fishing situation, the Rhino Knife functions very effectively due to its compact design, line cutter, action opening system, and heavy duty construction. I would highly recommend that anglers check out the available knives that Triple Eight Professional has to offer, especially if the company creates one of these high performance compact knives paired with a rubber handle grip.
