Siglinda 210mm Petty Saya. Our woodworker and knife sharpener Josh does these nice sayas that are made to fit knives that are slightly larger than the konosuke sayas. This one fits a bunch of 210 pettys on our site. If you place an order with the knife we will make sure it fits. If you are buying this saya for an existing knife you own we recommend you tell us which knife in the "comments" box so we can make sure it fits.
