Leather Wooden Handle Scratch Awl, Wooden Handle Scratch Awl Tool, Leather Sewing Awl for Leather Punch Hole or DIY Handmade

Q: Does this come with a cover?

There’s no “cover”, but there is a silicone sleeve for the tip.

Q: what size hole does it make?

I measured the widest part of the blade at 1.78 mm, but the hole it makes will depend of what material you are punching. Paper, leather, cloth (etc.) all close on the opening differently so the hole will always be less than 1.78 mm. I use mine to "scratch" (or score) leather when I'm transferring a pattern I'm working on. I don't believe you can find a tool that feels better in the hand than this awl for that purpose. If you want to make a hole in leather, I'd like to make some recommendation based on recent purchases. Both are sharp and accurate and leave a hole the size of the tool you are using. Both are phenomenal. 1 - https://www.amazon.com/dp/B07ZFF143H?psc=1&ref=ppx_yo2ov_dt_b_product_details was purchased to fill out a $25 requirement, and is the absolute bomb (unavailable currently, but will be back at some time) 2 - https://www.amazon.com/dp/B07K764B2G?psc=1&ref=ppx_yo2ov_dt_b_product_details was purchased based on a YouTuber's recommendation and is really nice as well (though pricey). You'll find different size choices on this page. I purchased the 1.5 mm and the 2.5 mm.
