Like Pyrography, engraving as a hobby requires very little outlay. With patience and practice highly artistic designs can be created on all manner of different materials, from leather or plastics, to steel or glass, from either simple lettering to intricate pictures. From a practical point of view, personal numbers or identification marks can be permanently engraved onto any object such as tools, bicycles etc. as an aid to recovery should they get lost or, worse still, stolen. Brennenstuhl engravers are powerful 25W units shaped to fit in the hand for maximum control even when a light delicate touch is required. The action is in the form of thousands of minute penetrating hammer blows. Both units are equipped with controls which vary the length of stroke, matching it to the material being worked. Double insulated, requiring no maintenance and rated for ten minutes continuous working time. The Brennenstuhl 25 Set is supplied complete with a hardened metal stylus suitable for most materials, a stylus adaptor for alternative points and a stylus for hard materials.
