Bread-Bakers v104.n028.7

Looking at  "Lame Bread Slashing Tool - Refillable" at:
http://shop.bakerscatalogue.com/
It appears that the handle appears to bend the blade, curving it slightly.
Is that what makes this lame actually work correctly?

Does anyone have the real "Lame Bread Slashing Tool - Refillable" from 
bakers' catalogue? Does the handle actually bend the blade? If so, is that 
what makes it work correctly?
