I have both. They are exactly the same.
Finished kives cost a lot more because they require human labor to build, and Scandinavian pay scales are much higher than here, then figure-in the cost to ship a boxed knife v. a flat stack of just blades.
Helle blades are exceptional in quality, sharpness and edge holding abilities.
You can also look at Lauri brand of blades, but Helle are nicer in finish.
