So in the kitchen or at dinner : spooning , forking your food is fine .
And you can cut , but you'd better not start knifing .
In the shop or on the job : hammering , sawing , scraping and even screwing is OK ...but knifing won't cut it .
The whole verb usage is primarily violently negative . To knife , knifing , knifed .
This makes some sense for the word "gun" , but the overwhelming use for knives ,in the modern word especially, has nothing to do with violence .
It's difficult to overcome prejudice when it is encoded in your native tongue .
Maybe this is partly why some people get upset with anyone carrying almost any knife ?
After all , who wants to be "knifed" !
