BLACK S. SHARP

* Every blade is checked a few times during production to avoid mistakes. We give 1 year warranty for breakage not every bend. We can also replace swords which bend on first use/sparring (and I do that without a problem) but after a few months of using and sparring minor  bendings are normal thing when forces are too big.  We can make it straight in our workshop, but we do not cover shiping cost. Frankly it is a minute of work and 80 % chances to finish it with foot and floor. Straightening the blades are common on every sport fencing training:

1.  Learn to properly thrust with feder and use its blade flexibility – hands up when you are hitting.
2.  Cut with proper edge alignment and avoid full force cuts to rigid targets – like Strong of partner blade/crossguard – if he parries your Weak just hit to his Strong – applying force does not work for you.
3.  Avoid charging to each other in sparring – it may easily  generate huge forces which can bend the blade.
