Sorry, I can't find a picture of the wenge handle that shows the reflections on the CA filled pores.I develop a slurry of oil and wood dust with 220 or 320 and the oil and leave it on the handle for a bit, it will become sticky. Then you rub it in the pores and off the handle. You are right, tru oil will become sticky fast, but you should be able to do it with cheaper oils and leave Tru Oil for the finish. I am interested in the pic of your CA finish, if you have some.
It would be great to do a comparison of all finishes on the same wood. @Greenberg Woods this topic could be interesting to you.
The comparison of finishes would be great. I might revisit filling the pores with oil and sanding dust after the summer. The process you describe is pretty much what I tried last time with the only difference that you start at a lower grit than I did. The way I did it has worked well for me on walnut, but the pores seem a lot smaller.
