KAI 502 Trapezoid Spare Blades, Box of 5

The Osmer 502-BL listing is a KAI 502 box of trapezoid spare blades, and the box in our photo is printed 502 x 5, which matches the five blades in our listing title.

Neither Osmer nor KAI publishes a page for this code that we could find, so the facts here come from the box and blade in our photo. The orange and black box carries the KAI name and 502 x 5, and shows a trapezoid blade with two notches along the back edge and a round hole in the centre. The loose blade beside it matches that outline.

A spare box keeps a fresh edge close by, so a worn blade can be swapped out when cuts start to drag. Check the outline and the two notches against the blade already in your knife first, because we cannot confirm which knife models this blade fits.

Compare other replacement blades by size, find a knife among our cutters and knives, see the full Osmer range, or browse everyday office supplies for the packing bench, the mailroom and the store room.

FAQs

We cannot confirm fit for any knife model. KAI and Osmer publish no fit list for this code that we could check, so compare the outline, the notches and the centre hole in our photo with the blade in your knife.
The KAI box is printed 502 x 5, which we read as five blades.
Osmer's own trapezoid blades, code 44U-BL, come in a hangsell pack of 10 and are listed separately. Osmer gives them as 60mm long and 19mm high.
Neither the KAI box nor any page we could find gives a blade material, so we do not state one.
