A stronger chisel than the slender "Paring Chisels". It is made with a plain rectangular cross section, ie without bevelled sides. The full name for a bevelled edge chisel is actually "Bevelled Edge Firmer Chisel". This is half-way between the two in terms of robustness.

A jig saw is really a narrow blade supported at one end by a mechanism and at the other end by a quick-release attachment to a spring or an arm of some kind, but the use of "Jigsaw" for "Sabre Saw" seems very common.

Distortion of timber due to shrinkage.
A standard taper much used in engineering. Lathe centres and drill chucks fit very accurately into tapered holes formed in the driving shaft (or the tailstock). The fit is so good that friction alone transmits the power. It can be dangerous to mill with a tool held in a chuck fitted with a morst taper without a draw bar.
A flat-faced piece of wood holding a scribing point. For its useMarking Gauge Tips.
The entire aperture in the sole which enables the blade to touch the wood.

A pair of parallel strips of wood which are placed at each end of a surface. Sighting across the tops of the rods will reveal whether the surface is twisted or not.
Visible light is part of a long spectrum of radiation, ranging from radio waves to cosmic rays. Sunlight can be split into a spectrum of differing wavelengths, ranging through the bands of red, orange, yellow, green, blue, indigo and violet, that we see in rainbows, sparkling jewellery, colours on oil films and so on. Just beyond the red end are the invisible infra-red rays which can be felt as heat, and at the other end, ultra-violet rays whose effects can be experienced as sunburn and by their photo-chemical and germicidal effects. A sun-lamp which of course emulates sunlight, gives off an intense white light rich in ultra-violet light, but with a greater effect.
A device for squeezing hot glue from between the veneer and the ground.
These are wood cells, interspersed within the fibres, but proportionally of larger diameter. They can often be seen on the surface. The patterns they make can contribute to the visual appeal of the wood.
On a 12 point saw, there are eleven teeth per inch, but twelve points.
