A Quality Piece From A Quality Brand
I've had my eye on CJRB for a while, hoping they might have some models go on clearance, but no luck. I guess when you make a good product they don't end up in the clearance bin! Their products are striking. That's what draws me to them. Lots of companies make good quality knives at a good value. But they are the same as everything else that's out there. This model is different. It looks great in red, is extremely fine in detail and well put together. The wide blade makes slicing no problem, where a standard knife would struggle. It opens fairly easily, and I noticed a little oil on the joint. Many companies don't even bother to set up the knife for use - they are full, require lubrication, tightening of fasteners and screws. CJRB sends you a knife you can use day one. It's not a big deal to have to do a little pre-field maintenance, but it's a nice touch when you don't have to do so. It looks even better than the picture. I like unusual cutlery, and there are not really any good imitators of these pieces on the market. I'm really impressed with the attention to detail. It didn't come in a fancy box, and frankly I would rather they put the money into the cutlery rather than the box. A nice sheath would have been a good touch for a middle price-point knife, but I will likely carry this as a pocket knife. The attention to detail, the tolerances are superb. If you are looking for a good quality blad that stands out, CJRB is definitely a good choice that doesn't break the bank. As far as value, I've rarely gotten a knife of this quality for less. There's one company out there making even cheaper knives that are high quality, but their tolerances and finishes are not as fine. Altogether I have to say that not only is this piece worth the money, but probably double what I paid. There was a 10 percent coupon available which I used, and it really dropped the price to a level this knife simply doesn't deserve. If you want value for money at this price point, this is a great choice. The color ways were very nice, and I would have been happy with either, but the red looks outstanding. As far as utility, this can go in your pocket for every day use. The nice wide blade makes it ideal for some light food prep in the field. The blade has a nice matte black finish that will prevent things sticking to it. I can see this being great for camping, hiking, fishing, boating, arts and crafts, emergency and survival, just about whatever you throw at it. The blade is long and thick enough to handle field dressing an animal in a pinch, but there are honestly better choices for that. It's not going to filet a fish, but that's also a task that requires specific dedicated equipment that is ultra-thin and sharp. That's not the characteristics you want in an everyday knife. I'm superbly happy. I can see this being a durable, useful choice that will outlive me. I highly recommend it as a gift. Sure, your outdoors-loving family member has knives, but they probably don't have one like this. In summary, it looks fantastic. The quality is great, very well constructed, with precision fit and tolerances. This is not cheaply made. It's useful for a wide variety of tasks, fits in your pocket or clips to you or your gear. There's a hole for a lanyard, and I recommend it. Losing this piece would be a bad day. I love it, and I'm sure I will for the rest of my life.

Good solid knife
So I was skeptical about buying a knife without being able to try it out and hold it in my hands but this knife is definitely worth the money. I collected knives my whole life but I have never owned a CJRB knife but I’m super impressed with it. Super sharp, it’s heavy but fits well with the deep pocket carry clip, it’s not spring assisted which is the only downside to this knife but it’s still easy to open and the quality is solid. The colors go well so great buy I recommend it for edc

Opens easily and quickly & very good pricing for the quality
This knife opens easily & quickly. It is a sturdy knife and I am not worried when I need to cut something because this blade has a great edge on it. I wish I knew the blade angle of the CJRB FOR SHARPING. I’ve sent the manufacturer several requests for the angle of the blade so I could sharpen and it’s like Crickets over there at CJRB & company. That’s too bad that their customer service is not responsive as that would push them to the next level. I’ve got several of there knifes as I really like the blades , action, weight distribution and of course the looks. It’s too bad their customer service sucks. I did not change the rating of this or any of their other knifes based on their very poor customer service and or communication or lack there of. Good all around quality knife/s just don’t expect any answers to questions you may have about their product.

Stylish EDC
A great knife for the price. This knife looks pretty good and the quality is on par for the price. It comes quite sharp, is easy to use, and the color options are nice. The shape of the blade is not ideal for all uses, but for most, this is a great lightweight EDC.
