I got this book of needles from my Grandma. Can anyone tell me what the big scary looking ones are for on the left?

I don't have a clue, but it does look scary.

Doesn't look like a mattress needle...

Probably stitching leather on saddles, harness, and tack.

my guess would be leather....that is one heavy duty needle!!!!!

The curved needle is for upholstry. You would need it for recovering furniture.

i have some carpet needles that are curved.and a really, really long straight one i used for doing dolls eyes and such.
bags, leather, etc is what is says on the package front.

The long one is for tack work the two shorter ones are glovers needles, also for hide sewing. Lastly the curved one is an upholstery needle.

leather...the splay tip doesn't create a hole in the fabric but a small slit the closes up around the thread.

That curved needle is great for when/if you tie quilts.
