Does anyone know of a site that will teach me about the different types of
tools and what is best for certain jobs?

I was out weeding today and an old boy came past and made the comment that
I would be quicker and better using a hoe....

Is he right?
I was simply on my knees using a trowl....
But I would much rather use a long handled tool as I injured my knees a
while ago and getting on my knees can be a little painful after a while....

This may sound like an insane question but with the other comments about
the claw tools.....
