I tried holding it like a barrel grip but I have to keep my hand at a weird angle because my wrist hits the handle. I guess if I cut from underneath that wouldn't happen.If you got girly hands like me then you can use it like a barrel grip. If you got hulk hands maybe not so much.
The main reason I'm considering the barrel grip is because the handle just feels way too small and chintzy. I've never even used a barrel grip and both my bosch jigsaws are d handle but the Carvex just feels weird.
One thing I would have to get used to is an on/off switch versus a variable speed trigger. I have a habit of throttling down as I start and stop the cut.
