Any Info on this vintage knife?

[Vintage love]

My great aunt gave me her full storage locker when she moved into a nursing home. Going through some of my late great uncle's things and came across this old knife. I feel it is very old because of the wood handle and bits and pieces I could find while researching on internet. It is a J. A.HENCKELS knife and at base of blade under the symbol and name it says the GERMANY. I was up most of the night but could not find any record of this knife. It also has a jagged teeth like thumb hole which i found interesting. I am intrigued by this very cool knife and would love some info on it. Sincerely, Erica.

I opened a free account at Photobucket and upload my photos there. Then I copy the IMG code they provide and paste it into my post here.

the jagged thumb hole sounds like a matchstriker thumb notch. Henckel's is a famous kitchen cutlery company and at one point also sold pocket knives, though I have no idea on dates etc.
