Falx Curved Bimetal Plunge Blade - Canadian Woodworking Magazine

An improved oscillating blade that provides exceptional performance.

Falx Curved Bimetal Plunge Blade

The most widely used blade for oscillating tools is the bi-metal blade – a multi-purpose blade designed to cut through just about any material, including wood, drywall, plastics, fiberglass, non-ferrous metals, and thin gauge metal. We reviewed bi-metal oscillating blades from seven manufacturers and found that those from Bosch, Fein, and Imperial gave excellent results.

Falx is a new entry in the oscillating blade market. The blade is manufactured in Canada from premium Austrian bimetal steel, and distributed by Fein Canada. Currently there is only one model available, which I had occasion to try out.

In the photo above you'll notice that Falx uses FEIN's 8-star and 12-pin mounting system, which means that you can use the Falx on virtually any oscillating tool without the need for an adaptor. One of the benefits of this design is that it transfers optimal power from the oscillating tool to the blade.

As you'll find with most manufacturers, the blade is laser welded to the blade holder. Fein blades are welded in five places while the Falx has only four welds. I've used Fein blades for years and have never experienced a blade breaking off the holder. I hope the same holds true with the Falx.

The Falx has a curved cutting edge, which isn't a new concept – Bosch uses a curved edge on it's OSC114F plunge blade. However, the curve on the Falx is noticeably more pronounced. The curved blade does a much better job when it comes to plunge cutting as it distributes the load more effectively, providing for a cleaner blade entry.

Curved cutting edge with bi-directional tooth orientation

What really sets the Falx apart though, is the bi-directional arrangement of the teeth. Half the teeth point in one direction, half in the opposing direction, which means the teeth are cutting in both directions as the blade oscillates back and forth. With this design the blade requires less power when cutting, which anyone who uses a cordless oscillating tool will appreciate.

Hybrid tooth design

The Falx blade also features a wavy tooth design. Again, other blades use this design. On the Falx blade you can see crimping or stamping marks where every group of 3 teeth are bent to alternating sides. Tooth set is very slight, and the set only extends slightly past the gullets. This design helps clear debris quicker, and reduces heat build-up.

The teeth are coated with a high hardness, low-friction ceramic coating that prevents debris from adhering to the blade, especially should the blade overheat.

(L) Clean plunge cuts; (R) Fast nail cutting

I used the Falx to make a series of plunge and crosscuts in dimensional lumber, plywood, hardwood, and laminate flooring. The cuts were very clean, and chip clearance fast. Because of the curved blade design, there is no skitting around when the blade initially begins cutting, which makes the blade easy to guide. As per the recommendation from Falx, I swept the blade side to side while cutting, and noticed that chip removal, and blade control, were much better. Falx also recommends that you install the blade at 90-degrees (right photo above) and reduce your cutting speed by about 20-percent.

I also used the blade to cut some galvanized nails. While the Falx blade did a very good job, I don't think it cut any quicker than the Fein 151 blade.

The Falx comes in 3-pack for $56, or about $19 per blade. It's a blade I can highly recommend, specifically for plunge cutting.
