help sealing white ash knife handles

I'm using figured white ash for 3 hidden tang knife handles. Even though these are learning/practice knives, I'd like to protect the wood in case they are used outdoors or in damp conditions.

I have some danish oil with a medium stain. I tested it on a scrap piece of the ash. The open pores absorbed so much that the nice sharp grain and color gradient became a muddied mess. Any suggestions for a clear sealer to use for white ash?

Some background:

I recently purchased 6 blade blanks to learn about putting handles on knives. The basic knife blanks are 3 full tang and 3 hidden tang. If these go well, I'll move up to making stock-removal blades then possibly into forging.

I finished 2 of the full tang knives using micarta scales cut with a scroll saw. They look decent if you don't look too close. Once my sanding technique is better, I will re-sand both of them to be much more presentable. Nick Wheeler's sanding videos on youtube had some good techniques.

I have ash handles profiled and drilled for 2 of the hidden tang blades. It's certainly been a learning experience. I've also taken a dislike to the small, soft guards that came with the hidden tang knives. At least one of them will be replaced with a canvas micarta guard that can be sanded with the handle. It's hard not to scratch the soft, polished guards.

The reason for using ash is I found a nicely figured table leg at a home improvement store for $5. I saw it and immediately thought that should be turned into knife handles. It made three 5" blocks that were 1-5/8" square. Ash is straight grained, but this was sawn at a slight angle to the grain. The figure on the sides is nice.
 
Try using dye as opposed to stain. Stains are pigment based with the pigments being developed from literally dirt. Dyes are small molecules that usually accentuate grain.

Most top coats come in varying shades of yellow. Fine Woodwork did an article on that 5-10 years ago which was very useful. Lacquer is one of the clearest/least muddying, but is also not especially durable and poorly water resistant.
 
I prefer to use CLEAR Danish oil no pigment or stain. The clear will bring out the subtle grain structure and not make it look muddy. Apply a heavy coat let it soak in for 30 minutes wipe it dry and apply another coat soak for 15 minutes then wipe dry. Allow the handle to sit over night then using "0000" steel wool lightly buff use a tack cloth to remove fine dust then apply another coat of oil let it stand 15 minutes then wipe dry and repeat over night drying one more time with steel wool and tack cloth inspect closely for any little wood fibers sticking up knock those down with steel wool. If the finish is smooth now you can apply a thin coat of oil and rub it in with a wool sock or use Carnuba wax and buff to a nice smooth shine. Both finishing techniques will give you a good barrier against dirt, grime, and moisture...Good Luck and have fun!
 
Mike Williams did a cool demo at the ABS hammer in a few years ago where he was finishing ash with epoxy and charcoal dust. Mix the carbon into the epoxy, then scrape it on to the ash to fill the pores. Sand it off, and the pores are still filled black. It was a cool look.
 
Ash has large, porous grain and will require a lot of filler to make it smooth. It does not make a bad handle but if you want a smooth finish you will need to fill the pours with something. Danish oil will not fill the pours but does help seal the wood. You can fill the pours with a colored pigment, a colored paint works great if you want to enhance the grain. Apply a full, thick coat of paint, allow to thicken near dry and scrub off at right angles to the grain. Let dry, sand with the grain until just the pours have color. I would suggest next using multiple coats of something like Tru Oil to finish off as you can build up a finish as need and it is easily refinished as the handle wears.
Hope that is helpful.
 
Thanks for the information and ideas. I will try clear danish oil, filling/coloring the pores, and tru-oil. This is a good chance to experiment.
