Don't Forget Your Shoe!
This might seem simple at first but for reciprocating saw users, it is really something to consider. One feature on your reciprocating saw is the adjustable shoe. Using this feature creatively will allow you to be as effective as if you actually got two blades in one. All you have to do is one simple thing when you start to use your saw for your initial cut.
Prior to starting the cut for the first time, extend the 'shoe' of you recip saw out as far as it goes. Make your first cut in that position. You'll need a blade with enough length to be effective. As you cut, you'll see that the bottom two or even three inches of your saw blade are not used at all. That is to your advantage. The stroke on a typical recipe saw is about 3 inches. With the shoe extended, you cut out on the blade and not at the teeth along the base of the blade.
After making one cut or if your cutting is slowing because the saw blade's teeth are worn out, just stop and adjust your shoe to the fully 'in' position. Now, with the same blade on the saw, what you just did was essentially the same thing as if you had changed blades. By retracting the shoe in, you are cutting on the teeth that have not been used thus far. You now have fresh teeth at the base of the same blade to make more cuts.
Why not be effective and be smart?
With the shoe retracted back to the 'in' position as shown in the first image, you have fresh teeth on the same blade that you have already been using for your initial cutting.
The fresh teeth shown in the second image are at the base of the blade and allow you to essentially get two blades for the price of one.
How many times, especially in training, have you thrown a recip saw blade away only to realize that you only used the first three inches of teeth at the base of the blade. The teeth along the rest of the blade probably still have their original paint on that.
Learn to use the shoe feature on your recip saw to your advantage and see if you don't 'double your money' on your saw blades!
Never even knew that was adjustable. Thanks!
