Selling due to my father's retirement. This is a used item that was used for work. He said it doesn't cut because it hasn't been used for a while. Total length: Approximately 17cm Blade length: Approximately 6cm Finger hole length: Approximately 2cm I don't know what percentage it thins. I don't know the inches, so please understand that there may be some error as this is a rough measurement. Since it hasn't been used for a while, maintenance is the responsibility of the buyer. The photos are everything. Please refrain from purchasing if you are nervous about used items.
