Rosewood Bridge City Tool Works CS-1 Rare?

[Derby Matthews]

Just a quick question - there's a solid Rosewood Bridge City Tool Works CS-1 Centerscribe on Ebay now (not the knife-handle JUARA wood). has anyone ever seen one of these before? My juara wood one still binds up sometimes even after all these years, but it works well on curved pieces.

Also, can anyone tell me when the next Boston area Lie Neilsen Tool Event happens?
