It is a pipe smokers knife. The long pick is to loosen the tobacco if you pack it too tight. It also works to remove any tobacco that might get caught in the shank of the pipe. The blade is not sharp and it has no point. A point might make a hole through the cake at the bottom of the bowl and cause the wood to burn through. The blade is mainly used as a scraper to ream down the cake In the pipe so it doesn't get too thick and crack the bowl.
I would guesstimate it to be from the 1980s.
I would say it is good quality but not expensive; approx $10.
