Hi. I recently brought a spoon carving kit consisting of a whitling knife (opinel lock knife) and a crook knife (frosts) and the person who i brought it from said that because there would be a slight delay in my order he would compensate by changing the knife to a Iisakki Jarvenpaa sheath knife. I only paid £20 for the kit so could anyone tell me what this knife may be. I googled it and about a thousand links came up. Any help would be very much appreciated .
