Yer modern joiner is obviously going to be faster but can get caught out when hand tool skill could save the day e.g. if on site somewhere, etc etc. All of a sudden rip sawing by hand or freehand sharpening with an oil stone, become essential!
One very well used tool was the joiner's axe, which has been just about forgotten.
We can still sharpen and use saws ( although im sure that'll dry up eventually )
Its true that new chippies wont have the same experience that i had whilst starting out, so are very much more reliant on power tools with less hand tool experience.
When i learnt worktops, we didnt use a router, the masons mitre was by hand. Took a while but was how i was taught.
Also true that understanding wood and its grains / effects of these sections is becoming lost. I trained about 25 years ago and I was not taught anything about wood selection/ cupping etc ( either at colledge or by my old boss )
The only time ive worked without power was a kitchen fit up on the moors with no electric. Back then i had a battery drill and 2 batteries, which lasted a day ok. The rest was handtools. About 20 years ago.
With jigsaws etc, we dont need axes....
