• Jigsaw Blades

• Miniature jigsaws are great for model building and art projects.

• Jigsaw

• Fancy models add a speed control, and a knob to select whether the blade oscillates front to back as well as up and down. This one has an annoying knob where you select the material and type of cut you want, and it automatically sets the type of blade movement, on the assumption that you’re too dumb to figure this out yourself.

• A quality model will be well-balanced, and can run quietly and smoothly.

• This looks at first like a table saw, and then like a scroll saw, but close examination reveals that it is actually an upside-down jigsaw with an over-sized base plate. It takes standard jigsaw blades, which stick up from below, but otherwise behave just like as in a hand-held jigsaw. Accessories let you use it like a marginally effective table saw.

• This is a very basic jigsaw from some decades ago. No options, just on or off.

• Battery-powered jigsaws are great for ad-hoc cutting in and around the house. They don’t use much power compared to other kinds of power saws, so the batteries last.

• Jigsaw

• This jigsaw has a knob on top that lets you turn the blade independently of the body. With simpler models you have to turn the whole tool.

• There are a lot of types of jigsaw blades available. As with hacksaws, no one sharpens these: they are considered a consumable item. This set conveniently labels each blade with the material it is meant to cut, so I don’t even need to add captions to the picture.
