My understanding is that Nordost WILL reterminate their cables! But they will not cut lengths. So if you want to reterminate your I/C's from RCA to XLR or vice versa, or your speaker cables from spade to "Z-plug" (their much improved variant on a standard banana plug) Nordost will do this. The newer Valhallas have a much heavier spade, which has a set screw that allows the removal of the spade, exposing a "Z-plug", so that you can use either termination with their new style of speaker cable connector.
You can tell if it is a legitimate retermination, by checking for shrink wrap over the terminations that specifically says "Valhalla", NOT "Flatline Cable". The Valhalla shrink wrap boot is only available from the factory, when they reterminate. A cut Valhalla cable, reterminated elsewhere, will have the "Flatline Cable" shrink wrap termination, which is sold to sources outside the factory. VALHALLA CABLES SHOULD NEVER BE CUT TO MAKE SHORTER LENGTHS!!!! Other than the fraud issues mentioned earlier, cutting a Valhalla cable will probably degrade performance, due to the strict matching and quality control used in the manufacturing process of this exceptional cable.
To add to the confusion, Nordost made a very small number of early Valhalla I/C's that did NOT use the Valhalla boot, for legal reasons that I will not get into. Nordost will also deny that these exist, but they do! No quality difference, but stay away from the unbooted 1 meter lengths, as these are most likely to be cut cables, as previously described. Don't expect to find these unbooted longer lengths, as only a handful were made. But if you do, these should be sold at a discount.
