I keep two old box knives in the kitchen junk drawer. One has a regular blade on it, and the other has a hooked blade because I think they’re safer and run less risk of damaging the stuff inside the box. But sometimes, you just need a regular box knife. They’re both old and handle rough, but they have seen a lot of use.
Last night I was painting. While trimming some masking tape against a hard edge I realized the blade on the regular box knife was a bit dull, so I went to change it. While flipping the blade around to the unused side, I noticed there were no more spare blades in the handle.
Today I bought a new pack of blades. They purport to be better quality and will stay sharper longer than the original set of blades that came with the knife, but I guess we’ll see how that holds up with use.
While adding the new blades into the handle, I decided to go ahead and clean up both knives - get all the tape residue out, and clean the internals. Then I gave the slightly rusty patina’d slide mechanisms a couple drops of 3-in-1 oil. I also gave the blades in the handle a drop along their sharp edges for good measure.
They open and close very satisfactorily now.
Can openers is what did it for me.
In 2015 I needed a new manual can opener. The local big-box stores had two basic styles. A cheap, all metal one that was just stamped from a single sheet, and a more expensive one with better handles.
The more expensive one had previously rusted and began to look nasty within a few years.
Amazon had a bunch of different styles at less than the price point of the more expensive one.
I bought one. It was fine. I didn’t love the operation. It cut the whole top off from the side, rather than from the top in a downwards cut. The sharp edges were on the can rather than on the lid. It would catch the paper labels and sometimes wad them up into the can while you cut. Cans with no air space would leak when opened.
Anyway. Replaced it in 2019. Amazon still had a broad selection, but all except for obvious crap was as expensive as the local big box store’s expensive option. Wound up going to a smaller local(ish) bulk foods store and bought a cheapo restaurant one for less than Amazon’s/the big box store’s similar offerings. Minimal rusting to date.
