Hi,
I have one of Paul's knifes also,,, it's a great knife, one of the best I've ever used. Pauls' blades are very sharp, & holds an edge for a long long time! I also got a knife from Bryan,, http://leatherworker.net/forum/index.php?showtopic=28149&st=0&p=176719&hl=+copper%20+swivel%20+knife&fromsearch=1entry176719 He made me one out of copper,,, with I believe a Henley blade,, it's a great knife. I have a couple blades from Bob Beard, which are fantastic! I use them a lot. I have a knife from Henley,,, great knife & blades,,, well worth the money. I'm a swivel knife junkie,,, I have several kinds of knives & blades, including Rubyat & Ceramic, which to be made usable, must be sharpened & honed a lot.
There are lots of good choices. Both Paul Z. & Henley are quick & easy & Great to deal with, & have great products. You will see the difference with the first use,,, well worth the money!!
I hope this helps,,, Ed the"BearMan"
