Flextest: Check sharpened edge with flex test in case it fails add 10°C to the tempering temperature and try flex test again after 1 h tempering

Note: avoid tempering temperatures higher than 200°C because the steel will loose to much of its potential and between 200 and 300°C the is a area of low toughness (blue brittleness)
