The Scotch Dispenser looks just like a Scotch tape dispenser. It is supposedly more comfortable than it looks though.

I LOVE <img src="/ubbthreads/images/graemlins/thumbup.gif" alt="" /> neck knives particularly skelly ones and really want a black or even better comp AD. They are much handier and easier to conceal than folders and being able to use INFI or SR101 for everyday use is wonderful. Really when you think that we only use our big knives a few times a year but the neckers I use every day. It is a much better use of cash as well. The flatness makes for a much much lighter and much easier to conceal package. The Swarden is only 40 grams.

The reason there is no Scrapyard necker is S7 would not be a good steel for the job. The 154 would be near perfect though so we may see one in the future though.
The Hairycarry and Muppy's are great knife designs but a bit thick and heavy for neck wear. With a good sheath and clip they can be worn like a folder which works very well.
