I came across this sentence in an anime I am watching. I am wondering if this is some kind of expression that means something like "no matter which way you look at it"
I can't seem to find anything in my searches. Could someone please explain this to me.
The context of this sentence is someone trying to sell a knife to a merchant. The sentence is the reply of the merchant while inspecting the quality of the knife:
押しても引いても切れやしない まぁ、ガラクタじゃな
