Something about a razor sharp object hanging around my neck that makes me nervous.
Not HC, but considered A G Russell’s Hunter Scalpel a few years ago. 2-1/4” blade, 4-3/4” OAL, push button thumb release. Orderred, received and ultimately returned one. Although about as safe as a neck knife could be, just didn’t see it as practical.
For cutting at the muzzle in the field, use my sheath knife - second hurried shot is the exception, so dealing with a sheath knife is no big deal. At the range use a straight razor. May take 25-30 shots in a session and a sharp straight razor is perfect for the task, at least for me, when trimming patches at the muzzle.
Whether HC or not, just don’t see a neck knife as practical or safe.
