Yes, it doesn't take much pewter to make the knife very heavy. The last time I made one with a pewter bolster I packed the antler hole with epoxy, leaving about 1/4 inch at the top for the pewter to fill. Score the tang and the inside of the hole with the dremel and it will hold just fine even with that small amount of contact.

I like the look of your knife. The extended finger guard is a touch I've never considered. Very nice. I bet it will polish up beautifully.

You may already know this, but when you are pouring pewter don't forget to smack the bench top a few times as it cools to loosen any cavities that may form in the molten pewter. Learned that lesson the hard way.

I like the look of that blade. What's it made of?
