Probably. They’re likely original to the house, so circa 1948

I kept pushing it off. I’m getting a new roof this year so I’ll have those installed with the new gutters.

Not a bad idea. I do love a performance

What kind of set you use? I’ve had a whetstone but got tired of it cause it takes a while to set up and soak, and it was hard to make a good edge on my curved kitchen knives.

Now I use a 3 stage coarseness “drag the blade through the V groove” sharpener, usually only use the 2 finer settings, but it seems to wear out and get a less fine edge over time.
