There are other kinds of water drop pickaxes, which are used by foreigners. The shape of foreigners' hands is relatively large, which one is more suitable. We use ordinary ones in China. There is also a big triangle pick, which can be used to play guitar, but it is specially used to play bass. The voice is dull and you can't play fast and high-pitched SSOLO.
In terms of materials, the usual pickaxe handles are a mixture of PVC engineering plastics and ordinary cheap plastics. Donlop uses a material called celluloid, which is a leader in electric guitar picks in all aspects. Other good draft picks include IBA draft pick, fender draft pick and signature draft pick of many masters. The material is more advanced and expensive, and is generally used for collection.
