John Wilson Pattern 99 Figure Skating Blades - Brand: John Wilson - Model Name: Pattern 99 - Size: 8 Thank you for viewing. I purchased these for around 70,000 yen and used them for 7-8 months, primarily practicing double axels and triple jumps. How about it, if you'd like to try the Pattern blades? Please refrain from purchasing if you are concerned about minor scratches or rust. Thank you.
