I really like that roach belly on the right. Where'd you get the blade?

That one actually belongs to my seniormost grandson. He won it in a 'hawk throwing competition at a Rendezvous last year. If I remember correctly, it was made by the blacksmith at Jacobsberg, an historic site just a bit northwest of Easton PA, also known as "Henry's of Bolton". I'm finally getting around to putting a decent handle on it.
