I want to check out the t-blades sometime, but there are many cons though some pros.

CONS

You have to buy new ones every month or so

You can't get the sharpened to what you want really, and come really sharp

Most skates don't have them so you have to spend $160 for a pair

Your lhs might not have them

Sometimes you have to change them yourself which can be annoying


Any anyone would like to add, add!


Pros

You don't have to relay on the skill of the sharpener

They are one of the lightest skate holders on the market

They increase your glide

They save you trips to get your skates sharpened

They don't break as easily as TUUKs

Once again add to the list if you can!
