Optima Fixed Tip 18S Spear Point Shader, Small. Renamed from the old 13SP tip. This new shader looks a lot like the #5 spear point but has squared off edges (not sharpened) and it is bent at a 45 degree angle for shading. Great for when you need to shade an area that's in a tight spot. Recommended in place of the old #13 pen for flat work pyrography. Available in larger size 18 & smaller size 18S. The 18M is the same shape and size as the #5 Spear Point except it is bent with unsharpened edges.
