yes yes yes a GOOD sheath can and will sell a knife for sure.
I refuse to sell one with a sheath under $195.00 a buddy of mine that's been make for as long as I have
said to me one time, don't go down on the price it will sell,
and I say now, it's just waiting for it's owner to come a get it, but he needs to see it first..

put every one you make on the site then weed out some later that you don't like but show as many as you can customers are funny

well not really sometimes...
Gib just a thought here..
if you can't sell them for a low price,, go up,,, not down sounds strange
but sometimes it's the low prices that will keep them from selling,, they'll say
what's wrong with it ? to them selves..
a guy I've been helping with knives for the last 2 or so years found that to be true.
he said it's weird..a good money back guarantee is a must also..
. you're not in competition with the Pakistanis and the factories,,
sure if it's to high, that can be a problem too but you need to be comparable to other knives in that over all
range of product, hand made product, .
the shows help but as you I can't hit but a very few.
I forgot to mention put customer comments on your site also
They are a big plus. I didn't see if you had one or not. but beef it up it can't hurt.
get permission to list their phone numbers and e-mail addys this will at the least say to customers this guy has some Backing and is true ..it's your own show...
what do you have to loose if they an't selling anyway giving them away just leaves a bad taste for them..
edited to add
on your AVAILABLE for SALE page you have no knives AVAILABLE to buy there? maybe the sold Gallery would fit better .
and it may help it to get personal and say (I) not (we) when you talking about the knives you make yourself,
it's a better feel for the customer that it is a knife made by you and not by others not listed,,just some ideas ..
I mentioned this to Jay Maines about his site a long time ago too and I see he changed his from we to I. I hope it helped his sales too...By all means colab's should be said as we as in (Chuck and I) ..we to me is a factory
