I've had a few Swaty's - a two line one, a three line one, and an 8 inch two line one. I have since gotten rid of all of them, because I didn't use them. Normal length barber hones are alright, but I don't like that they are so short; it means having to do more passes. The longer one fixed that issue, but I never really reached for it. I think barber hone's are a great, inexpensive option for minimalists who just want to maintain an edge, a very useful tool for anyone, and a possible AD to boot. But, if you already have other stones that will do the job, what's the point?

To be honest, I try to keep my hones to a minimum. I have three that I use in my normal progression - King 1k, Dragon's Tongue, Asagi. I also have a PHIG (People's Hone of Indeterminate Grit aka C12k) that was my finisher before the Asagi (the Asagi was a gift - I never would have spent that much on a hone for myself). I also have a BBW/Coti glued combo (also a gift). I don't use the combo anymore (replaced by the DT and Asagi), but it was a gift (and I don't think I could sell my only coti...).
