My grandfather always carried a knife very similiar to this one, and he was no gentleman. Nevertheless, the Gentleman's Folding Pocket Knife is simple and handsome.

The wooden handle is ergonomic, which houses a 440c stainless steel 3.5" locking blade. You can open and close the knife with one hand thanks to the linear lock.

The knife has received a ridiculous 4.9/5 stars from reviewers there, and it's a great find for under $20. This is a nice practical and inexpensive knife for your everyday carry.
