That's a very nice pen! The main wood looks like the bloodwood I've got. The accent wood in the knot looks like it could maybe be a mahogany or padauk?
Padauk?
I suspected it was aluminium, i did one once where i had some thin black plastic sandwiched between 2 bits of aluminium, had a blowout on the lathe and never completed it, your pen looks great though and the Paduak is a rich red colour that looks spectacular.Ok, I take back my previous post :redface: I found another blank that I had matched up with this one and its Padauk.
Tiger- Can you believe the outline on the knot is soda can aluminum? :wink:
