The Wilson Pattern 99 is a (3) THREE Radius Blade.
The MK Phantom is a (2) TWO Radius Blade.
The Wilson Gold Seal is a (2) TWO Radius Blade.
These Radius Variations are what truly make a difference in the way a Blade feels as you Skate, Glide, and cut Edges. These are called the PROFILE of the Blade.
Until recent times, it seems that the most important design feature of an Ice Blade was the Toe Pick. While yes, the Toe Pick is important for Jumping, Stopping, and many other types of transitions, it is the Running Edges and the Blade Rocker that really make the most differences.
The positioning and length of the Rocker, or the extra curved area that should be under the Ball of the Foot, will determine how well you can spin (and find your center of balance) as well as how your long flowing Stroking Edges will glide.
As with most things in this life, personal preference or the Coaches desires for you, come into play and will impact your decision as to which Blade style is best for you. This information can help you to make wiser choices.
When it comes to the Toe Picks, the bottom Pick is what controls the ALL Important LIFT ANGLE.
The Drawing above was provided by Rob Rudolph of Paramount Sk8s and reflects the PROFILES (or copies of Blade Curvatures) that Paramount has available. Most Blade manufacturers today use these three Profiles as the basis for most of their blades, so this information does not appear to be proprietary as it can be measured and replicated.
