|A small non-magnetic screwdriver blade is ideal for adjusting magnetic compasses.This blade is durable, corrosion resistant, and can be put on a key chain until needed.|
Works as advertised. Works well to swing a compass.
Its small and what I love about it, is that I always have it with me because I keep it on my keychain.
Small item which makes it difficult for me to handle easily. A brass screw driver is probably a better tool for making compass adjustments. Thought to be over priced as very little material used in making of item. Shipping cost high due to packaging material not really needed for such a small item. On the plus side, the item is small enough to tape to side of compass so I can easily keep track of it when needed.
Kinda expensive for a little sliver of copper, but its well-made.
