If you want to use any of the alternative textures, you need to Import them via Jed's Half-Life Model Viewer.
Heres how:
Open your model vith JHLMV (File>Load Model...> Either v_knife.mdl or p_knife.mdl) and click the Textures button.
Select the knife textures and click 'Import texture' and choose one of the alt textures. Save your model 
(File>Save model as...) and add it to your counter-strike folder.
