The Companion HeavyDuty Military Green is designed for heavier utility or Bushcraft work. The carbon steel blade is about 4 inches long, 3/4" wide, and .126" thick. That's about 1/8", The sheath has a belt hook that can be snapped over the belt. It will securely fit belts up to 1 3/4" wide. It can also be fastened over wider belts, but doesn't lock as securely. The handle is a bit longer than the regular Companion model (4 3/4" vs 4 1/2"). The knife weighs just over 3 1/2 ounces, or 4 3/4 ounces in the sheath.
