Tool, symbol or both?
The bits on this pendant are based on actual bit sizes - including an IKEA standard tool - so 'a bit cross' can be used for light jobs. Just remember the steel isn't tempered like 'real' tool bits and tolerances may vary.
I recommend using it with a red leather cord of about 78 cm/ 31 inch.
