From South Africa, André Thorburn is in business for a long time now and generally recognised for his craftmanship and nice designs.
Two years ago I got the chance to get me a one off made by him. A button lock from the early 2000’s. The previous owner told me that André had told him never willing to make another because of the work involved.

In fact it is not a button lock. It is more a liner lock with a button to move the liner outwards to unlock it. The knife is a kind of Gentleman’ish folder with a damascus blade, aluminum bolster and very nice polished wooden scales. Fit & finish is what you can expect from a knifemaker with the reputation and stature André is known for, Opening is done with the thumb studs and closing with the button. Action is very smooth. Below a video I made 2 years ago when I got this piece. Don’t pay attention to my English; I know it isn’t good.
