As the adhesive used enamel or plain nail Polish. Of tools enough to have scissors, pliers and a razor blade from a safety razor.
Electronic devices based on microprocessors and integrated circuits are less sensitive to the parameters of the supply voltage. To ensure the safe operation of these devices use voltage regulators with protection. In many power supplies is reduced to cut power to the circuit if a short circuit in it or a sudden increase in load current. Such, for example, the popular voltage stabilizers КР142ЕН5. 
Reground the blade plane for beginners is sheer torture. Not so just manually set the correct angle between the sand around and a piece of iron and withstand this angle throughout the sharpening process.
