Hi all, I just got this J Lecoultre frameback, it comes with 3 blades. Is this like a Feather (you use them and throw them away) or you can actually hone these? If it's like a Feather, it will be more like a collectible (vs. a user) and I will be selling it. If it can be honed, I plan to hone and test shave.

Thanks
Ivo
