French & Indian War Sword/Dagger?

[murph21]

New member here. Hoping to get some feedback from you experts on this short hunting sword or cuttoe re: possible age and origin. Purchased in US. Thinking probably 1700s? Has a worn engraving of what looks like a prancing cartoon-like lion (I think? Could be a hunting dog?) along with the phrase in French "Rien ne m'arette" which means "Nothing can stop me" in English. Same image and phrase on both sides of blade. Stag or antler handle. 23 1/2" total length, blade is 18 1/2". Bronze cap and hilt. No makers marks. Should I assume this to be French or French-American made?Any feedback greatly appreciated!
