We offer violin bow tips in plastic, casein imitation ivory, fossil mammoth ivory, ebony, Elforyn and in Tip Armor™, our trademarked polymer composite.
Elforyn is a mineral plastic that is made in Germany and we machine the bow tips here in our Ohio shop. This is a strong polymer/plastic - much stronger than the plastic and casein tips but not as strong as the nearly indestructible Tip Armor. Elforyn works easier than Tip Armor and actually works easier than any of the other tip materials.
Tip Armor™ Violin family member bow tips are made of AMW-814, a polymer composite. This recently developed polymer has been formulated for strength and flexibility and engineered in a way to allow artisans to work the material with ease utilizing standard carving and bow making tools. This material bends with finger strength and holds its bow tip curve for application without the typical process of soaking and press-forming. Simply bend the floor to the needed curvature and glue into place. Then shape, sand and carve as you would mammoth ivory or other materials. Several glues work well including hide glue and superglue (CA glue) which works very well.
Our fossil mammoth ivory (FMI) is musical instrument grade material and is of the lightest color and most blemish free stock we can find.
