I shall put anything I find interesting or worth commenting below.
Planes

There’s also:
- Scrub plane: you could modify the blade of a No. 4 with a rounded end to make ‘deep’ shavings in wood for truing and smoothing boards faster. Wood by Wright has good pointers on this YouTube video.

- Block plane: a hand-size model that you could technically put in your pocket for quick adjustments, and the like.
- Corrugated plane: a plane having the sole grooved in lines parallel to the sides.
- Thumb or Finger plane: small planes for fine/detail work (used in violin making – also called “Luthier Plane” in some circles/vendors).
- They can be smooth (flat) or concave (round).
- They could have also “tooth blades”.
- Squirrel Tail (Palm) plane: smaller than block planes.

- Shooting Board plane: for easing shooting boards on the end-grain.

And if you want to go even further on this rabbit hole, you could delve into Japanese planes (kanna) or any Japanese woodworking tools, methods, and techniques.
Conversions
- Conversion from inches to mm:

Sooo easy…(not). One inch is divided in 16 parts. Sometimes they say 1/2 is 13mm, however, it’s 12.7mm, but let’s live with that.
Pointless discussions
- Resting planes in the ‘side’ position
- Primary and Secondary bevels
- Sharpening and sharpening angles
- The need for using the bending iron for the purfling
- Wood choices (“mine’s better” mindset)
- Measurements less than 1mm
- Violin makers are not ‘common’ woodworkers
- Japanese woodworking better than Western
- Imperial x Metric
- Use of sandpaper over rasps
- Secret varnishing
- Pure machine, pure manual, hybrid
- Pricey x budget tools and materials and quality
- PVA x Hide glue
- Gouges inner x outer (in-cannel x out-cannel) bevels
