Razor saws are a type of back saw, which includes finely-pitched crosscut teeth. These hand saws contain disposable/replaceable blades - as it is very difficult to sharpen their teeth due to their small size.

Razor saws come in a variety of teeth-per-inch (TPI), with more teeth indicating a finer saw blade. The average teeth per inch of a razor saw are 15 TPI. The finer blades can go up to as many as 60 TPI. The blades are primarily used for cutting plastic, wood and soft metal to a depth which depends on the depth of the blade. With a double faced metal edge, the top of the blade will only fit in particular slot sizes of miter boxes. These hand saws have a rigid back or holder which allows the blade to be able to cut straight lines that are useful for miter cuts in wider pieces of metal or wood.

There are various benefits associated with the usage of razor saws. First and foremost, the benefit of using these hand saws is that the presence of the thin blades allows them to cut soft metal, plastic or wood with a very small kerf, maintaining a neat and clean edge on both sides of the cut. Used with more teeth per inch, makes these saws a perfect alternative for fine inlay work on instruments or inlaid dollhouse furniture, railroad cars, track and plastic airplane kits. They also serve the purpose of cutting rod and thin tubing, mitering, slitting, and sawing of very delicate parts. Most of these hand saws cut only on the pull stroke. However, you can also find a huge assortment of razor saws with replaceable/removable blades which can also be used for push or pull strokes.

Without any doubt, these hand saws have become a perfect solution for hobbyists, notably Model boat, Model aircraft and Model railroad enthusiasts.

Power Tool Buying Guide For Saw Blades

!±8± Power Tool Buying Guide For Saw Blades

The first thing to remember when buying a saw blade is the arbor size. The arbor is the center hole in the blade and that must match the arbor size of the saw. On any saw remember to read your owners manually to see what blade size you will need for your saw. Saw blades come in a variety of sizes, types and materials.

Type of Materials used to make blades:

Steel Blades - Good for cutting softwoods, but will dull very quickly on hardwood. Inexpensive.

High-Speed Steel (HSS) Blades - Harder than the steel blades and will stay sharp longer. A little more pricey.

Carbide Tipped Blades - More expensive than the Steel and HSS, but they stay sharp longer than both. Good for hardwood cuts.

Abrasive Blades - Abrasive material used on these blades for cutting masonry and metals.

Diamond Blades - The tips of the blades have real diamonds and will cut through glass, concrete and ceramic tile.

The saw blade does the cutting. Spend a couple dollars more and invest in a blade that will stay sharp longer and give you a better cut.

Types of Blades

Gullet is the space between the teeth of the blade

Ripping - A ripping blade has few teeth and a large gullet for good wood removal. Used for cutting with the grain of the wood and will produce a ruff cut.

Crosscutting - Has many teeth, usually more than 48 and a very small gullet. This is used to cut across the wood grain and will produce a smooth finish.

Combination - Usually has a series of four to five teeth similar to the crosscut and is divided by a very large gullet Used for cutting with the grain, against the grain and miter cuts.

Plywood - Usually has a 100 or more teeth and as the name implies is used for cutting plywood.

Hollow Ground - This blade is ground thinner into the body than the teeth to prevent binding. Used for making smooth cuts across the wood grain.

Dado - This is manufactured as stacked, one piece or two piece adjustable units. Used for cutting grooves and dados in dimensional lumber and sheets.

Thin Kerf - Used for easy cutting and will not waste as much material. This is used for cutting dimensional lumber.

Abrasive - Used for cutting tile, masonry or even steel.

Diamond - Very sturdy and strong blade used for cutting tile, concrete, glass and ceramic materials.
