All folders for sale thru dealers are made at factories. Every factory are dealing with spec's that is - within certain limitations, the knife is acceptable at the price it is given.
This means that a very cheap model will never offer firm and 100 % well made functions. From a very expensive model your demands are higher, of course.
Like all manufacturers, we had the possibility to decide upon the overall quality level for the U2 model and we stated that this folder should work as a EDC, offering a very good blade, a firm, reliable lock and an adjustable lateral play. Regarding the axial play, we decided to allow a little play for being able to keep the low price. This play will never affect the safety and as well will never harm the handling of the folder.
We had the possibility to from the very start state that this folder should be 100 % perfect with regards to ALL specifications but that would have lead to a very high price and, compared to the handle material, it wouldn't match very well.
So, the U2 is a good folder sold at a very attractive price. You cannot find a folder equipped with a laminate powder steel blade at this price, I'm sure.
You will always find samples of any cheap or expensive folder which is better in any aspect compared to the U2 but if you add all qualities, including the price, I'm quite sure that the U2 is superior in its price range, like all other Fallkniven models.
With regards to the number of U2 we have sold, I find that the U2 is having a fail percentage of 0.4 % so, it seems like this product is well made.
Buying from a internet dealer is in general much cheaper than buying from your local store. The risk you take is that you cannot check the products before you buy it - and that's up to you.
So, don't look at the price only...
