I have been considering getting a Sheffield made single blade Barlow for a while, and have decided to get one from Arthur Wright and Son. Sounds easy, but when I started to investigate more fully I have discovered that they make two versions of this pattern, one with flat bolsters and handles and the other with round bolsters and handles. Has anyone had a chance to try these out or compare them in person? I am kind of leaning toward the flat version, as it looks like it would work best for pocket carry, but it is hard to tell from the photos I see on line if there is much actual difference in thickness between them. Any input would be appreciated, thanks!
