The standard problem with these sets is that users ignore the bit setting instructions and burn both the bit and the chisel because they fail to leave the correct gap between the two. Just a little warning that if anything turns blue, you should look in the mirror to see the cause.
For easy chisel sharpening, a pair of diamond hones is recommended, one for the basic grind and the other to put a micro-bevel on chisel corners. The corners need the higher bevel angle for strength.
