A crossbowman or crossbow-maker is sometimes called an "arbalist" or "arbalest". Trahaearn also obtained Norman arbalest crossbowmen for additional support for his army. This is an example of canting as Balestra, means "arbalest" or crossbow. These new siege equipment's include catapults, mechanical bridge layers, arbalest machines, and battering rams. The term "arbalest" is sometimes used interchangeably with "crossbow". Kaiyodo introduced the Arbalest and Laevatein into their Revoltech line in 2007 and 2008. In comparison, an arbalest could only deliver about two bolts a minute. A large weapon, the arbalest had a steel prod ("bow").
