Manual on sharping hand tools
Link to a website with fairly inexpensive gardening gear. Many times they are auctioning hand tools. This company (www.ebth.com) will pack it up and ship it out -

Good thing is that these are inexpensive lessons You want to avoid buying the saws with bent blades, because they have been abused and are almost impossible to straighten out. Worse, the structure of the metal has been compromised in order for a bend (or wave) to set in the blade.
What I have done, with limited success, when I mess up and bend a blade on a saw, is to very gently work it across my leg in the opposite direction, trying to shift it back to straight a bit at a time. The trick here is to go easy and gently, because you have to go past where you want it to end up in order to get progress against the existing bend. Go too hard, and you bend it the other direction.
And the ultimate problem with straightening blades - metal fatigue. Every time it goes from a set position to a new set position is a bit of breakdown in the structure of the blade.
