Go to the Norton 4K and see what happens, pryamids are useful when you're learning but if it's a big blade they may not do enough each time you make one. You may need to stay on the 4K side for a while. Is this razor hollow ground or a bigger grind? This may be a factor in getting advice and you may need tape if it's a half hollow, wedge, etc. You should be able to pop hair on 4K though, Norton 1K usually gives a hard time with arm hair popping.
