Yes and I enjoy it. However:

For best comfort and enjoyment I have found the following to be true for me:

1. Smaller, lighter knives are preferred for neck carry.

2. Neck strap needs to be comfortable. Wider, within reason, is better. Pull-chain type straps are awfully uncomfortable and noisy.

3. Neck strap should have some manner of breakaway feature. 550, for example, without a breakaway is trouble waiting to strike.

4. Knife orientation is strictly personal. Decide whether you want to draw the knife across you abdomen or your throat. Mind the sharp part! I have carried both ways. My sense is, blade up for martial use, blade down for utility use. Either way, train thoroughly.

5. Kydex sheaths are best for blade up carry. Leather will loosen and drop your knife.

6. Blade down carry requires less critical sheath fitting. Leather or Kydex are good choices, as are other materials such as web strapping. The trick is finding the sweet spot among size, balance point, and noisiness. I personally prefer a pouch-type sheath for blade-down next carry, covering more of the handle and scales. I like the extra idiot proofing, the extra security and coverage, and the less tacticool style.

7. There are plenty of talented makers offering these sort of rigs. Or you could "easily" make one yourself. Expect that you may need to go through a few before finding the right combo.

HTH. YMMV. Blade design and role, obviously, play huge roles in guiding your decisions.
