I received both my Single Knucks today. 1 for each hand. I absolutely loved them the moment I slipped them on. Like they were made for my hands. I collect all sorts of knucks in all sorts of materials and these are revolutionary game changers in world if knuckles. Thank you for designing these and bringing them to fruition! They will be trusted daily pocket candy for me. Cheers!

These things are well made! Bought 2 sets, one for my nephew who is taking off to the military soon, and I got an everyday carry set to keep in my vehicle, hope to never need them, but better to he safe than sorry! Medium size was perfect for me!

Great knucks

I loved them so much ordered another one after first order. Quality Knucks 5 stars. I have only good things to say about these No Metal Knuckles.
The customer service was great also. Thank you for everything

Fixes well

B-nuck single

The site says this was a “factory second,” or blemished product, but I can’t find the flaw.

Great knucks!

While I absolutely live the fit quiz I am sad to report that my fingers that are more sharpie-esque in girth didn't quite fit the medium recommendation for women. They did however fit my sister and she loves them so I just ordered myself a pair in small :)

I was very pleased with the comfort, fit and finish. I think this will be an effective tool with little break in time. Well done

Guy that gets no response from support
Good product but no support

I ordered 2 of the single knucks B stock, but only got one shipped. I emailed the support address twice about not receiving the entire order and did not get a response. The B stock product is fine just some rough edges and slight color variance for the B stock, but they will work. The single feels nice in your hand, and the Ergo even more so. The classic does not feel as good as the other styles.

Solid Se- Defense Tool

The Ergo knuckles have a great fill and would undoubtedly prove to be a good self-defense option. Hopefully, I will never need to use them, but I like knowing I have them available.

Large is big for me

Can I return the large pair for a medium or can you give me a great seat on a pair medium respectfully

I just took a chance and ordered one of the b-grade knuckles and I love it! I will be in the look out for more

Fits naturally in my hand

I purchased both the single knuckle and traditional brass (plastic) knuckles and prefer the single knuckle for fit, ease of handling, and natural feel, as well as concealment. You won't be disappointed!

Don't hesitate to buy

Even though it was a B Grade knuckle the fit and form was still great. I will be buying more to toss in all my vehicles. Great for non permissive environments.

great idea

I got one of each size, If you think you have big hands the Xl is still oversize.

Great church safety option

Like all other defensive safety assets, you hope you never need them but this is America post-2000, and your product is a most welcome less lethal option.

Not bad

Very nice keep in my pocket all the time because I love in riff neighborhood. I wish they made a size between medium and large.

Medium too Small and Large too Big

The medium size is too small for my Social Finger as it gets stuck. So, I will be returning it soon. Thanks for trusting me by allowing me to try it on without charging me.
The large size fits my Social Finger but the others are too big especially the Pinkie and Ring fingers.
It seems to me that you should make the finger holes different sizes instead all the same sized, i.e., the Social and Index fingers should be about the same size but the Pinkie and Ring Fingers should be smaller.

Liked them at first

Ordered 2 single Medium single knucks and enjiged them for a few days until one litterlly just split open down the middle and now was in two pieces. Didn't do anything rough with it so my confidence in these has been shaken. Will buy only metal pairs from now on
