Knives with 25mm snapoff blades
This is the only snapoff knife I know in this size. It has all the advantages of that type of knife ~ replaceable, retractable blades and six opportunities for a quick change of sharp point.
Postage ins extra on this item at the large letter rate. Spare blades are not easily found on line ~ a pack of ten cwould not increase your postage costs!
