I was thinking of using this cartridge as a daily work shaver then switching back to the tighter shaving blades when I want to be BBS. I assume they will be a lot less irritating to the scalp and I'd be able to buzz it a little quicker without fear of scalping myself.
Answered my own question-there are no holes in the cartridge to attach the headblade adapter to. I tried it with the Bump Fighter razor and the results weren't very good. It did do a nice job on my face though-I may try using it more during the week and then switch to a double blade for weekends.
Glad you were able to answer your own question

I personally have never heard of bump fighter before.
