Need help finding a knife

[captaincalamari]

Id really like to get a knife shown in the pictures but due to Uk laws I might accidently commit a warcrime, if anyone can help me find a knife like one of these (that oblige with the laws) that would be greatly appriciated. I know the pictures arent all the same but primarily looking for something with not the typical blade. Perhaps a curve in some area, or a saw-back design or anything. Thank you!

And one that hopefully doesnt cost too much but still has good quality, I find the last 5 more to what I am looking for rather than the first few
