Corby Bolts are a stepped Bolt Set that literally Holds the handles against the Tang.
They make the handle material impossible to get off without destroying the Bolts.
Mosaic pins are just pins.
They hold Nothing and are just Epoxied into the Handle and Tang.
They offer no advantage and are only decorative.
I guess we are all not communicating well on this Pin/Bolt thing.
On knives that use Corby Bolts - ALL of the handle sets are Countersunk with the Step for Corby Bolts.
If you order Mosaic pins - We cannot use the machined handle set - We literally have to totally hand make a set of handles for the knife from a rectangular Slab Set.
It will not be as even side to side as the machined set and will only be held on with the Epoxy.
In short - I don't want to do Mosaics and you are getting a finished knife that can have the handle slabs come loose with hard use.
On the Small Knives that take 3/16th pins we will put any pin you want in them but the larger knives that are now set up for Corby Bolts are a major issue to me.
Now lets cover materials for Bolts and Pins.
Corby Bolts are usually Stainless Steel but I will be switching to 6061 Aircraft Aluminum Corby Bolts in the Future. - We do have Brass Bolts but will not use them unless the Customer pre-orders the knife with them.
Pins are either Aluminum Solid - Aluminum Hollow - Brass Solid or Brass hollow.
Mosaic pins are TOTALLY Hobsin's Choice.
I do not order specific Mosaic Pins - I just order them - Whatever Ann Sheffield Sends me is what we put in.
You cannot specify a specific Mosaic pin. You get what we Get.
I do not Stock Bronze or Copper.
Sometimes the 1/4 inch Mosaic pins have little Copper Tubes inside them - Again - it is an Accident if I have them.
I hope this Clears some of this up.
