When im sniffing off the back of the hand I have two piles, and sniff one at a time. The left one first with the right nostril, then the right pile with the left nostril.
One long line along the back of the hand. Left nostril first (it senses better than the right though it is usually a little congested), tilt the head slightly as I move along the line to finish with the capacious right nostril. Immediately dust with a handkerchief.
I snuff one pile with left then one pile with right and in a few minutes repeat the whole process.
I use the back of the hand more than the pinch but I must be an addict or something…my piles for each nostril are at least the size of my thumbnail and I’ll repeat immediately after getting the second side done if it doesn’t “feel” like enough.
I’m going to have to practice the back of the hand technique - I feel like a ninja saying that. 
Anything I can do to get more snuff up my nose has to be a good thing. Edit: Whoa! Talk about overdoing it! 
Depends on what I’m sniffing actually. If I am using a Pschol Ozona snuff then I tap to my hand because the tin seems to be made to do that. I do two small (or large) mounds and then sniff. If I am doing my W.E. Garret Scotch or Sweet I go with one pinch and switch nostrils.
@ddavelarsen LOL!! You ARE a Ninja!! Of course your ninja mask has nose holes for you to snuff through…lol!!
I’m with Chrishansen, it depends on what I’m sniffing. If its a tap box I’ll use back of the hand, of course. From tins, I usually use the tip of a small buck knife, same way you’d use a snuff-spoon, which I only use on snuff. I sniff schmalzler from the back of the hand ‘cuz its easier to get it up the nose from there (if that don’t work, I use the ol’ shovel-it-in method). I got a snuffbox recently from Mr.Snuff so I’ve been working on the pinching method but it just seems messy to me so far, I must need more practice…
I pinch. About a pea-sized amount for each nostril. When I use a tap box, it’s back of hand technique (LOL @ddavelarsen 's NINJA) and I wear a thumb ring, so I tap the box against it and it helps knock the snuff out of the box and onto my hand lol. Mostly I pinch and sometimes I use my fiance’s spoon that came with her PC tripletech. That box is so damned cool. You guys need one. I do too for that matter…
Practice with the back of the hand technique is coming along, but I’m still getting way too large piles! LOL! That’s gonna take some getting used to. I wonder if I’ve smeared snuff all over my nose; probably. Yeah, hankie came away pretty dusty. I made a spoon for my tripletech that fits right in the hole. It’s the larger of the two in the picture. There’s a picture of it snug in its hole in the box too. I like it a lot better than the spoon that came with it. My tripletech is the box I carry McC Clove in, and it’s always running low… 'Cause I love that snuff. 
@Transisor You will find that nunchucks constructed of broomsticks and attached with clothes line will help you achieve many things you desire in life, including your fiance’s snuff.! Nice spoons, Dlarsen! Can’t get much tighter than that!
That Dave is a crafty fella. I can attest to this first hand from the awesome ebony spoon that he sent me…beautiful craftsmanship!!!
schmalzlers I use a pipe nail and shovel it in. almost all others I use Dave’s spoon and put it on the back of my hand. depending on strength of the snuff it may be 1, 2 or 3 spoons per nostril. edm
I always use the back of my hand. I usually take a big pinch, make a bump and do one nostril. Then i do another pinch for the other nostril =D. The only time i ever pinch is with D. white, which in that case i take a big pinch, put it under one side and drop the adams apple (creates the perfect ammount of suction) then do the other.
