This is a DENSAN electrician's knife. It was used for 5 months, but not every day. The case has some scratches, but the knife itself is in good condition, with a sharp blade, a good handle, and no looseness, so there are no problems with its use. I've been using a different electrician's knife since then, so I'm selling this one. Please refer to the photos and consider purchasing. Also, if you only want the electrician's knife, how about 900 yen? Thank you very much for reading to the end.
