Review by: Chris McNamara ⋅ Founder and Editor-in-Chief, OutdoorGearLab ⋅ April 4, 2010  
The Black Diamond Hotwire was the first carabiners we know of made with the revolutionary "wiregate" design. At first, they scared people. Today wiregate biners are among the most popular because they are light, strong, and reduce gate shutter (the effect of the gate partially opening during a fall). While this carabiner once was the only one, there are now many to choose from. Still this remains a solid product at a good price, and Black Diamond only made it better when the company shaved of 20 percent of its weight with hot-forging technology. The Wild Country Astro earned similar scores to this product across the board.

OutdoorGearLab Editors' Hands-on Review


The Black Diamond Hotwire scored well in most categories. It scores above average for ease of clipping. It held three figure eight knots very well (it's roomy). As with all biners with the wire-gate design the gate is less likely to get frozen shut on alpine routes and the slightly hooded nose helps protect gate from getting inadvertently rubbed/pushed opened.

As with most carabiners with the unprotected wiregate design, the notch gets caught up on the bolt hanger when cleaning steep routes. The notch also gets caught up when racking nuts. If you want a wiregate, but you're concerned about snagging, consider the Wild Country Helium Carabiner or Black Diamond Oz Carabiner.

Best Application

This is an all-around carabiner light enough for trad or even big wall climbing but just the right medium size to be easily to clipped on a sport route or with a gloved hand on an alpine route.

The Black Diamond Hotwire is toward the good end of value. Not one of the cheapest biners but not the most expensive either. Because it is so popular, you might find it on sale in our Price Finder.

I love this biner!

First off: BD actually makes these in the US still, and this is a plus in my book. Not all BD biners are made in the US (ie, livewire is made in tiawan, couple others are made in china), but the new, forged Hotwire is! Yay for american manufacturing!

Second: I've never been a fan of the size of the neutrino or other micro biners, but I have been a fan of how light they are. The new hotwire is great though; it's the weight of the neutrino (37g) but still maintains the full size of a standard biner. Super easy to clip and not get your finger stuck in the gate, unlike the Neutrino or the Oz. This is probably one of the best weight-to-size biners on the market for ice/alpine use with gloves on.

If you want a biner that is super easy to clip and is light weight yet full sized, this is your biner!

Bottom Line: Yes, I would recommend this product to a friend.
