For parts / Junk S-Blade RM-F403 (S) Inner blade K-W21U Outer blade K-F33S Brand: Hitachi S-Blade Cutting method: Reciprocating Junk due to deterioration of rechargeable battery Purchased new, used by my father. It seemed to work when connected to the cord, but he said he stopped using it because the battery deteriorated, and the usage time became shorter without the cord. I'm not sure if it still works reliably because I don't know where the AC adapter is, so I'm selling it as junk. Please utilize it for parts, etc. Please refrain from purchasing with the intention of using it with an AC adapter, as the operation has not been confirmed. We may cancel the transaction after checking before shipping.
