Just took a look at the Baileys axes. Is yours flat ground at 16 degrees??? No issues there? Secondary convex?
It came with no secondary bevel..which did cause an issue with rolling. I added a nice fine secondary, and its much better now. I have to use a good bit of care where I live anyway, if chopping pine, the knots are like stone, and can chip or roll any fine edge easily.
As far as productivity. I have spent a good bit of time with axes of all shapes and sizes. I like a 3.5 very much indeed. I have played alot at the idea of timebersports, so I find I lean towards the heavier heads, when dealing with single bits. My 5lb Hytest is a pleasure to use, for me anyways. One of my favorites is a 3.5 double , I picked up off of the "BAY" for a good price.
Most of my axes are Flea Market finds and stuff I bought on Ebay. I wouldnt buy a "new" axe, that you can find in the stores nowadays..they have terrible grinds IMO.
Of course, their are exceptions, some of the older hardware stores still carry quality. YMMV.
When I started collecting Axes, I spent ALOT of time searching out old heads..sometimes I bought lemons, but most cleaned and handled up well. The hardest part of collecting old heads was finding good handles. I lucked out 2 years ago, and bought some single bit hickory handles in bulk for a deal..I only have one left..and am waiting for the right head for it...LOL
