My mother-in-law had one that I frequently sharpened for her. It would go dull cutting through soft butter. Nostalgia aside, there are a lot better kitchen knives available that actually hold an edge.
Right on.
At 52-55 Rockwell it's clear why everyone I ever found was dull. I find them regularly in rental cabins, always dull, same with thrift stores and "antique" stores. Great knives as long as you are careful what you cut with them, know how to sharpen, and like to sharpen often

I find the old Cattagarus brand kitchen knives, sometimes chrome plated, are a much better carbon steel and hold an edge much longer (IIRC it's got some vanadium). They are no longer produced, but can often found cheaper than Ontario/Old Hickory knives in thrift stores, gun shows, etc.
