get the one which has a v shaped entry , it,s easier to get the blade in ,
don,t bother with the blue one with 2 extra compartment,s for extra blades
mine have two holders , one on the front for a 5 inch blade with handle attached , never seen these for sale so i made my own ,easy you need an old bucket which is no use ,remove the holding part ang glue it to the front, just remember to drill a hole into the main bucket so it does not fil up with water , you need to see it !! it,s the best design and so are my pockets i designed my own so you don,t get your scrim wet at all.just cut the sides and add another piece to give more volume
