Saw blades play an essential role in the life of a watchmaker

It is regarded within the trade that Gold Shark Swiss-made blades are the best so no wonder they are the blades of choice for a true craftsman.

If you are new to blades, here are some basics: 

The blades are sold in a bundle containing 12 blades . Twelve bundles (144 individual blades) are called Gross. Gross is really 12 squared. Great Gross is 12 cubed (1728 blades). There is also a Small Gross which contains 10 bundles (120 blades). 

A blade is defined by its thickness and the number of teeth per centimetre of length. The more teeth, the finer the cut.  Blade number 0 (zero) has 20 teeth per cm and it is regarded as “medium”.  

From there, the sizes go up - 1, 2, 3 to 8 and down to 2/0, 3/0, 4/0, 5/0 and 6/0. 

Bottom line: the thinner the sheet you cut, the finer the blade. And while you can cut thick material with a fine blade, the opposite is not possible. 

At the moment, we carry in stock blade sizes 0, 3, 5 and 6 which covers medium to coarse, perfectly suitable for both watchmakers and hobbyists.  

Price: $6 per bundle (12 individual blades). Golden Shark, Swiss made.

Of course, hand cutting is an art form.  To make your cut perfectly smooth and make the blade last for 7 years use the cut lube AF Switzerland No. 180.100.  Apart from saw blades, the cut lube can be used with burs, drills, and gravers to virtually eliminate pull and drag.  Just dip your burs into cut lube with smooth cutting without chatter.  It comes in a handy stick dispenser.
