Extrema Ratio BF1 is a folding knife for everyday use: simple, essential and functional. The N690 blade is burnished, with a flat grind and a thick, durable tip. Extrema Ratio characteristic cut-out areas in the handle - give access to the opening “pins”, which don’t protrude from the knife when closed. The reversible clip is located on the back of the blade and engulfs its tang – making it discreet to carry. Employs a trustworthy linerlock blade blocking system.


The BF1 is available in several versions why stop at one!

    You won't be disappointed by the knife or the service!

    Posted by Paul on 26th Feb 2015

    This is my second BF1. As I already have the 'Desert' version I will spare you another monologue. You can check my review of that one on the HH site. I bought a second, because I was blown away by the first. I wish I could legally EDC it. I can only echo the feelings of Martin in his review and say that this copy is as flawless as the first. I have a great enthusiasm for ER products and so thought I would drop them a line using the contact page of their website. Unlike some production knife manufacturers I have contacted their reply was both personal and swift. As usual the service provided by HH staff members was second to none, something ER themselves recognised in their reply to me. I highly recommend the BF1 and possibly the BF2 if you need a little extra grip. I have removed my clip and have the knife in a Beneath The Stars sheath which is a perfect fit. Massive thanks to Richard for all his help at HH. A very patient, customer focused and knowledgeable asset to this company.

    Fantastic

    Had this knife a week now and used it hard and there are no bad points at all, it's perfect for my hands which was my only concern as there quite large, it's razor sharp OOTB, I have used it for skinning and other farm tasks, I'm going on exercise soon so I'll see how it preforms then, I know the price of these knives is high but it's reflected in the quality and I'm sure this knife will last a lifetime, again brill service from H/H, thank you.
