Nope a myth started by a certain Hone Pusher
Keep in mind you will find what Jimmy said to be true right up until 2 things occurred almost at the same time
1. A certain natural hone was pushed as being the most comfortable edge ever to touch a face
2. Somebody said "If you are not certain about what paste you like, use a Balsa wood strop to test it out first" next thing we know there are actually people selling Balsa strops and people are using them as a pasted strop..
Paste on Balsa works almost too well and the Pasted strop changed from a method of Mellowing the edge to more of a Refresh method..
Not really a bad thing as it adds more versatility to simple paste but the Mellowing aspect has obviously been lost to many of you newer guys :(
