delica endurance

[dee bee]

What method of sharpening, and at what angle would be the best at keeping an edge the longest on a delica thats being used to cut cardboard, plastic strapping, etc?

check out my thread on the paper wheels. they work great. check out the link to the vid in my sig line of a knife i made slicing newspaper. i have more vids at the link. i have made many members a believer in the wheels. i havent found anything else to work as good, not even home made.

A thin angle would work best for going through the material but you would suffer edge holding. A thick angle might hold a edge better but it would be like a butter knife trying to cut those materials. If you do a lot of cutting throughout the day a pocket sharpener would be ideal. If its a VG-10 steel delica you can take the angle back to around 15deg and be ok. A DMT fine mini hone would be a good start. http://www.knifecenter.com/kc_new/store_detail.html?s=DMTD2F

I thinned out the edge of my delica a bit. I then put in a 15-degree edge bevel with a 20-degree microbevel (just a few swipes on the fine stones). The microbevel noticeably reduces chipping when doing abusive things like cutting open steel cans (can opener was MIA).

I usually go without a microbevel, but my Delica is my beater knife.

It really depends how good you are at sharpening and how you like sharpening.

If I were to cut alot of cardboard and plastic straps, I would convex the edge and thin it out. If you're not a fan of sharpening but want decent performance and great edge holding, I would suggest a 20degree angle per side on a sharpmaker or lansky crock sticks.

What would be the difference between 40 deg. on the sharpmaker and convex sharpening as far as edge retention is concerned?

The convex edge if done properly will hold a sharper edge longer.
