It is a folding knife, that is correct. It is also a locking folder. I can't tell which type of locking mechanism it has. If the locking mechanism is in the handle, like where the blade folds into, that is a liner lock. Try to find the model number or name. I'm not sure, but that might be a tonto point. Do a search for Benchmade Tonto Folder and see if you can find the exact same knife. Make sure to include both the blade length and the overall length. Make a nice as to if the knife is used, and if it has, whether it has been sharpened or not. Lastly, the blade is a partially serrated blade.
