If you want to have some fun. Get a nice piece of FLAT stock (pine, whatever) has to be FLAT. Make it about 12-15" long and maybe 4" wide.
Take a piece of denim (cheap at a fabric store OR a pair of jeans that don't fit anymore

)
Take the denim and staple it down the long side of you flat stock (staples on the side) and streatch it taut over the stock and staple the other edge. Do the ends as well, stretching taut.
You now have a "Denim Strop" fine as is OR you can impregnate with diamond spray (no matter)
This will keep a scarey edge on your beloved Hinderer XM as long as you maintain the edge. Obviously, particularly hardcore bouts of edge useage may require something like the WEPS, EP, SM or a trip back to the Ranch for a Professional Sharpening but, this is a cheap effective strop that works very well.
Give it a try!
