BU680SSSB: TOPS/Buck CSAR-T Liaison
Buck Knives
Designed as a lightweight carry knife or tool for when your primary knife cannot be used, the Liaison can be the difference in any situation. The TOPS/Buck CSAR-T Liaison is a discreet lightweight carry knife that is rugged enough to get you through any situation. The skeletal design and Kydex sheath make it easy to carry and access. The Zirblast finish gives it a valuable non-reflective quality, while the handle has the hex hole compatible with the Hex Tool Kit that works with all the TOPS/Buck CSAR-T knives.

Continuing our dedication to bringing those who serve and protect tools they can count on, we continue to provide you with more TOPS/BUCK knives. Uniting two Idaho knife manufacturers brings over 100 years of development and manufacturing knowledge along with over 100 years of combined "real field time" experience into the creation of each TOPS/BUCK knife. Most who have used a TOPS/BUCK knife have been seriously impressed with these heavy duty designs. In 2010 our 095 TOPS/BUCK CSAR-T was rewarded for our innovative ingenuity when Field and Stream Magazine named this knife
the "Best of the Best" in 2010 under the Survival category.

TOPS/Buck CSAR 680
Solid performance. I was able to get this knife very sharp. I secured it to my EDC sling pack and have carried it daily for around 10 months now. I wrapped the handle in 550 cord and it works great. I've used this for heavy cutting & baton chopping some light kindling wood. For what it is this knife is amazing, and I would highly recommend it.

Cons: Weight, None
Good boot knife
Bought it for the hex lanyard and purchased the bit set with this as well. I wrapped the back part of the handle with the outer part of 550 cord for some added grip and glad I did, also took some cordage to the sheath for a "catch" knot to carry this in my jungle boot while hunting. This thing disappears in my boot and remains in the same place at the ready. Not a fan of neck knives but I have a few that I've repurposed as substantial boot knives for when I'm afraid I'd lose a folder out of my pocket.

Pros: Sheath/Scabbard, Weight, None
Cons: Blade Material, Blade Sharpness, Weight
good knife for the money
Planned to use for edc. It's very light and the sheath fits great with good retention. It seems perhaps to thin for it's design though it has good balance. I had hoped it would be a good thrower too but I think that is reserved for the big brother due to overall thinness and weight to length ratio. Edge retention is ok but expected from that steel.
