Usually they have different grinds, one for splitting, one for chopping Sent from the astropathic choir.
I've read that they used to have one side sharpened for felling and one side for rough work like cutting roots,
Not that this adds anything to the answer, but I just came across this old picture of double bit axes in use and I thought I'd share. (Image removed from quote.)

Sent from the astropathic choir.They did a study on the calorie intake of Swedish lumberjacks where they had old lists of provisions for camps as well as the number of men etc. I think they found it to be around 8000 kcal, that's four days worth of energy for an "average man" today. Crazy!
8000cal.....Well axe work ranks up with swimming and cross country ski as the hightest calorie burning activities.As for the double bit; I was told as said before the two sides had diffrent grinds. One for felling, one for roots and trail cutting to haul the trees out.
Something else to consider with each blade having a separate grind is that tree bark carries a lot of dirt. So by having a "sacrificial" edge, without having to bring two axes with you out of the logging camp to the work site, allows the logger to save his good/sharp felling edge for the clean interior wood...Peace, Rooster
I find the greatest benefit of the double bit axe is avoiding rebound. If I borrow one of Sparky Bloke's axes at a UK meet and the head isn't 100% secure, using a double bit head will ensure that if the head comes loose and flies off, there's a much higher chance of it sticking into Kirky rather than bouncing back and hitting me.Safety first!
Coz it looks wicked! Duh! 😝But yeah I heard that each bit had a different grind for splitting and felling. Respect for anyone that would handle a double edge tool. I've handled single bit/edge axes and machetes and I would probably split my forehead with the 2nd edge.
