Nice, simple, clean.
I think it strange that folding knives were no doubt invented to do away with the necessity for a sheath but a big folder piles up with everything else in the pocket so along came the clip to get it out of the pile and make it accessible like, well... a sheath. Then along came Jewell like high end knives that we didn't want to scratch and knife laws where the knife couldn't be in sight and we were back to the sheath to both protect, keep straight and conceal. Yours does the job better than the CRK version being wide enough not to fall into the pile at the bottom of the pocket. The only change I would make is to put the pen back in your shirt pocket and add a good light in the slot vacated by the pen.
Good job.
