Understanding Jeweller's Sawblade Sizing:

Jeweler's sawblades are fine, delicate blades used for cutting intricate designs in various metals and other materials. They come in a range of sizes and types to accommodate different materials and cutting requirements.

A standard blade for a jewellers saw is 130mm long, with an area at the end with no teeth on it where a clamp on the sawframe will grip the blade.

Sizing Explained:

The sizing of jeweler's sawblades is numbered, with each size having specific dimensions. See the product page for each blade for the available options and the sizes and teeth density available in that type

Basic Sizing Principle:

• In jeweller's sawblade sizing, the numbers typically range from 1, 2, 3, and upwards, with added "/0" sizes like 2/0, 3/0, and so on.
• The key to understanding this system is to recognize that the larger the number before the "/0", the smaller and finer the blade is.
• For most blade types, 0 is the approximate middle of the sizing range.
• 2/0 is often called a double zero blade, 3/0 a triple zero blade (00, 000 respectively) etc.
• Size 0 blades are sometimes called 1/0 - as it is a single zero.

The /0 numbering

• Standard sizes (like 1, 2, 3, etc.) represent larger, thicker blades. As you move into the "/0" sizes, the blades become progressively thinner and finer.
• For example, a 2/0 blade is finer (thinner and with more teeth per inch) than a 0 blade, and a 3/0 is finer than a 2/0, and so on.
• This trend continues as you go higher in the “/0” series. The highest numbers in this series, like 6/0 or 8/0, indicate extremely fine blades used for very detailed work.

Thickness and Teeth Density

The size of a blade is determined by its thickness and the density.

• Tooth density is the number of teeth per inch / teeth per cm as shown on the sizing table for the blades. Closer together tooth spacing will prevent material from being caught between the teeth.
• Choosing the right blade size depends on the material's thickness and the type of cut desired. For example, thicker materials will be faster and work well with coarser blades, while finer, detailed work benefits from finer blades.
• A way to determine blade compatibility is from the thickness of the item being cut, and the teeth density. Ideally you want to maintain at least 2 teeth in contact at all times to reduce blade vibrations when cutting.
• The density also impacts the smoothness of the cut, with greater tooth spacing causing a more rough surface on the item being cut.

Material Compatibility:

Harder Materials (such as Brass, some Bronze alloys, platinum, some white gold alloys, steel) will greatly benefit from the harder Pike platinum blades.

Softer materials do not require these harder blades, and as the hard blades break easier you should use standard Super Pike blade

Extremely soft items will clog the space between teeth on normal blades, so use of a spiral or skip-a-tooth blade will reduce blade clogging.

Spiral blades will cut on any side, however will tend to pull sideways when trying to cut a straight line. They are ideal for soft materials such as wax, shell and similar.
