Woodworking

Also for hand planes a #5 vs #4 are mostly down to preference, some people like slightly longer and heavier like the #5 and vice versa.

Same with saws I recommend a used handplane because tons of them exist and they should be cheap.

Make sure to get a usable hand plane, a good one should have

1. Cast iron frog and body

2. Comfortable tote (rear handle) and knob (front handle)

3. A Mostly flat sole, a lot of cheap planes are really badly warped and take forever to flatten, a mostly flat one will save you a ton of time.

4. No deep rust on the blade. Surface rust is fine but deep pitting on the flat side of the iron will prevent you from sharpening it properly

5. No cracks in the sole and body

6. Tight mouth (not super necessary if the frog is adjustable)

7. No major chips on the blade or god forbid a bevel on the flat side because someone's too lazy to properly sharpen it.

Some premium features to look for too

1. Handles made from premium or exotic wood (many Stanley's used rosewood)

2. Thick machined chip breaker and iron

3. many brass or bronze parts, even the body on extremely premium examples

4. Frog set screw, not a super premium feature and medium range planes should have it. The lack of one isn't a deal breaker though

5. Lateral adjustment levers made with multiple parts (cheap planes will have one stamped)

For restoring and tuning your plane I would highly recommend Rex Krueger's videos.
