Hand Saws.
C.K and Avit Hand Saws - Panel Saws
Sabretooth wood saws
The original Sabretooth wood saw is available in two versions; First Fix and Second Fix (see here for more details). The First Fix has 7TPI and the Second Fix has 11TPI, both with harpoint teeth.
The Sabretooth™ First Fix saw outperformed five of the leading saw brands in independent tests by CATRA (Cutlery and Allied Trades Research Association).
Cutting Edge Performance
The C.K Sabretooth First Fix saw was independently tested for cutting performance and sharpness by CATRA (Cutlery and Allied Trades Research Association).
The tests were comparative against five leading models of handsaw.
The results were averaged over the results of five of each type of saw. All the samples were independently sourced by CATRA.
The Test
In the tests CATRA measured the number of strokes required to cut through 100 controlled density and dimension blocks of chipboard to BS1919 with the following results:
-
The C.K Sabretooth™ First fix saw takes 21% fewer strokes than the next best saw.
-
Three of the remaining saws took between 74-93% more strokes to cut the wood.
-
The final saw: "... would not start to cut under the standard load conditions. The blade jammed into the work piece and stalled the motor drive on the first forward stroke..." so no meaningful results could be obtained.
What is the difference between the original Sabretooth saw and the more recently introduced Sabretooth trade saw?
The orignal Sabretooth saw is 13% heavier in construction and, as a premium product, offers the ultimate in long term performance. However, in general construction work the work is varied and potentialy highly damaging to the cutting tooth sharpness. Materials such as resin bonded laminate materials and nail embedded timber can cut short the working life of a saw dramatically.
Hence the volume sales of panel saws lies with low cost saws that are quite frequently bought several at a time.
The other issue is that in the UK there are regional variations in the length of saw preferred. Broadly speaking, in Scotland and the North East 20" saws are typically used, whereas elsewhere a 22" is more commonly used.
This is where the Sabretooth trade saw comes into play.
Sabretooth trade saw
The Sabretooth trade saw blades are made from premium quality SK5 alloy steel and feature induction hardened "hardpoint" teeth which stay sharp for approximately 8 times longer than non-hardened teeth. In addition, the teeth are triple ground, making them more effective at cutting on the backstroke.
The saws also feature dual component, cushion grip handles which offer 45° and 90° marking out angles.
There are three different saws in the Sabertooth trade saw range.
The T0840 20 and T0840 22, above, have 20" and 22" blades, respectively. These saws have universal teeth with 7TPI.
T0940 22 has a 22" blade with fine cut teeth, 9TPI.
Avit Tri-cut handsaw
In addition to the Sabretooth saws, there is the Avit Tri-cut handsaw which has a 22" blade with triple-ground and hardened teeth, and the rubberised handle also has 45° and 90° angle guides.
