will these work with a Milwaukee Fastback Utility Knife

should work with most utility knives

What size are these blades? product description shows the lengtht as 5.7 inches which doesn't seem right. It looks like it should be around 3 inches

I know this question is old, but I thought since I was wondering, perhaps others still do as well. The blade measures approx. 2.25”... and by doing a little digging it turns out that is equal “approx.” 5.7cm

Are these blades rust resistant? I keep 3 or 4 knives at strategic places in my extremely humid garage. When I need one, they frequently are rusted.

Mine arrived (one pack of three) with corrosion on them, The card that the blades was on had obviously gotten wet enough to fall apart though. I think they come coated with some kind of oil, as they tend to stick together. But they will definitely rust with enough exposure to moisture. I am sure this is the same as with any carbon steel based blade.

How many blades are in each of the five packs?

The listed pack size is the actual blade count. So 5pk is 5 blades, 50pack is 50 blades.
