I have this guy. Not sure where it originated from, it was in my dad's stuff and I liked it. Good for opening letters and in case you need to jab somebody at the front door. I really like the striped handle. I am not sure what's going on with the blade though, It looks wonky as hell.
The marking says "William Rodgers, Sheffield England" but it looks like they made a lot of these in different eras.
I saw one that has a *more* similar blade to mine listed as a hunting knife, but my blade is only 3" long. It seems way too small for hunting.. unless you're hunting chipmunks with it. But I presume this is what it was supposed to look like at one point.
