We get all sorts of engraving enquires at Tartan Trader, we recently had a request from a customer to engrave a small rock with his friends initials on it. As the rock had a fairly flat surface we were able to engrave it. This token means a symbol of love in many countries.
Then a few days later we were asked if we could engrave a metolius freenut key, this little gizmo is used by mountain climbers. Our customer wanted this engraved for a birthday present to his friend who enjoys climbing mountains in his spare time. Whether it is a rock or a hard place we like to engrave it!
