'sandblaster' originates from the combination of 'sand' and 'blast', where 'sand' refers to the granular material used, and 'blast' refers to the forceful stream used in the process.

'sandblaster' evolved from the concept of 'sand blasting', a technique developed in the late 19th century, and eventually became the modern English word 'sandblaster'.

Initially, it referred to the process of using sand to clean surfaces, but over time it evolved to specifically denote the device used for this purpose.
