You can do both. Shave with it, then sell it if you don't like it. I used mine today with a new Lord Platinum. Shaves equally nice compared to my Slim, plus I kinda like the longer handle. I've got another BB on the way - one with the metal bottom plate. Planning to dedicate my growing razor collection to specific blades once I'm done comparing them to my go-to (for now) Astra SP's.
