Frequently Asked Questions
Should new runners be profiled?
Yes. Profiling ensures your new runners match your skating preferences and helps maximize performance.
How often should hockey skate blades be re-profiled?
Most players should have their runners checked or re-profiled 2–3 times per season depending on sharpening frequency and skating volume.
Does taller steel improve performance?
Many players prefer taller steel because it can improve attack angle, edge engagement, turning ability, and runner lifespan.
Can I order these runners sharpened and profiled?
Yes. Tydan Blades offers professional profiling, sharpening, engraving, and hollow customization before shipping.
I heard about this company, while playing a tournament in Palm Springs.. there were some guys from Minnesota, had used them, and were very happy… I had had skates profiled in the past, but after contacting them, and having a 15 minute thorough consultation, my blades arrives ahead of schedule, and love the feel…this is my first year back, after I had both hips replaced 8 years ago, and am still trying to get my stride… these are definitely helping… would highly recumbent them to anyone… Happy customer here
