Knife ID: Help Needed

Via Cousin Dale”I need your help with a knife I bought recently……I’ve usually got a good idea of what I’m buying but this was a guess. I’ve included two pics. It’s a totally hand made knife with sheath, and the seller insisted it was a WW2 trench knife. I realized immediately it wasn’t any type of manufactured knife and the sheath was stitched with no riveting. The back of the sheath did have WW2 Canadian soldier info on it, along with where he was injured and when. Take at look at the end of the handle! “CS”! The emblem is different though, and looks like it actually says “CSE”. While Canada did have Canadian Special Forces in WW2 I could not locate this symbol anywhere. However, I did find several nearly identical knives under classifications of “Alabama toothpick” and “Arkansas toothpick”. Any thoughts? I don’t like to assume, but all indicators I’ve seen so far indicate this knife is actually a home made Confederate toothpick commonly used in WW1 and WW2. I thought perhaps you may have seen the emblem or understand this knife better than myself, and would appreciate any feedback!”
