So I asked an expert in this field, (Jay Fisher) about stone for handles, and this is what he had to say;
"Thanks for the invite; I appreciate it.
Unfortunately a lot of people think that gemstone is like glass. In the thirty years I've been
making gemstone handled knives, I've never had a standard mounted gemstone handle fail, ever.
Most of the gems used in custom and fine handmade knife handles are very tough, or they won't
survive being cut, ground, finished and polished with the heavy duty equipment the professional
lapidary uses. Some of the gemstone-handled knives Ive made have been used in combat.
My first gemstone handled knife? 1977. They've all sold. All of them. They're all gone so somebody wants them!
Where does this brittle concept come from? It happens because much natural stone has natural
fracture lines and cleavage planes. A lot of rocks are already invisibly fractured and a simple
whack with a masonry hammer will force the stone to break along those lines. Also guys have
seen obsidian which flakes at a regular angle, and it is stone, so therefore all stone is brittle.
These same guys would faint if they saw how hard and tough a piece of Brazilian Agate or jasper
is.
Cold? You bet; if you lay a stone handled knife outside in the cold, it will be cold because it's
more dense than wood and has no insulating ability. But neither does steel, and the steel or metal
bolsters, guards, and fittings are just as cold, in fact, they conduct the cold better than the stone.
But the stone warms up and then stays warm to the touch for a long time because it is dense.
Anyway, this is a petty little argument, because most gemstone handled knives are fine knives,
and not for everyday carry by the general population. Most of the general knife population can
not afford a gemstone handled knife, so are not interested. Which is okay, too.
There are, as mentioned, a handful of other makers using gemstone, and it has been used since
ancient times. Some of the Persians made exquisite handles of jade with inlays of gold wire, I've
not even seen the magnificence of their work approached today.
There is certainly a lot of long term interest in stone; in my own business I'm now approaching
four years of back orders, most of them for gemstone-handled knives. Its okay that gem-handled
knives are not mainstream. I kind of like that!
Lorien, I've made a lot of gemstone handled knives in my career, perhaps more than anyone. You
can see over 600 of them on my web site; Ive probably made well over twice that many. The
durability, value, and longevity of good gemstone can not be approached by any material. You
could make a handle out of solid gold, but it is soft compared to nephrite, you could cover the
handle with steel, it would scratch and jasper would not. In a thousand years, when the steel
blade is abraded, torn, scratched or corroded away, there will be the quartz handle, proud and
shiny, like the day it left the shop. Just look at the longest lasting monuments man has ever
created. They are all stone, not wood, horn, bone, ivory, or metals.
But you won't convince guys that dislike gemstone to accept it. I know, because I've fought this
battle for thirty years. That's okay. They can dislike stone, there are many others who love it, and
have made a great career for me and other guys who feel that stone goes with metal and wood
and shell and horn and bone and ivory, and even plastic...and hey, dont forget leather and exotic
skins!
Just to give you a personal head's up: there is some new manmade material coming out that I will
try for knife handles. It's a special ceramic, made to look and act ... like stone. Very, very tough
and hard...
Be well, my friend, and keep that bike off those granites!"
Thanks for the edgeucation, Jay!
