Hi! I'm Diane. The other one who posts on this account. I'm a bisexual menace and have been a pain slut for the last 10 years. I, too, am an owned & collared sub. Delilah is an amazing friend, cohort, and I love her dearly. Her designs are what I wish I had when first starting out in the BDSM scene.

We’ve been iterating on these for several months now and we’re almost ready to release them. Rigid or very slightly flexible (better for long term wear) collars. They have a strong magnetic closure which will not separate by accident, and can be secured with a Master Lock. #BDSM #Collars

This custom Etsy order is almost done. Thrilled with the way this ‘Pretty Pink Princess’ colorway is working on the 3/4-size Kelleynator hammer. And the pommel came out 👩‍🍳💋. #BDSM #ImpactToys #Maker #Thuddy

Custom request from Delilah’s Mistress and Owner. She wanted an Ophanim paddle head on a two-handed handle 😅 This is a “functional prototype”. Functional in that She will totally whoop my ass with it. Prototype in that I am not 100% sure yet about balance, weight, grip diameter, handle length etc.

Evil Engineering @evil-engineering.bsky.social · 05/09/2026

Just finished acetone-vapor-smoothing this Initiate paddle for an Etsy order using our custom built acetone-smoothing rig. As you can see, the process eliminates layer lines and leaves the finished part glassy smooth. This is delicate work, done by hand for each piece. See EvilEngineering.etsy.com

Just got a very special request for a Briar Rod. These are not generally available as they are truly for edge play. But for special (vetted) friends of Evil-Engineering, it can be arranged.

Evil Engineering @evil-engineering.bsky.social · 02/09/2026

Ready to head off to be reviewed 😁 4 paddles in 4 tiers. Unfinished/raw ASA (good), vapor smoothed ASA (better), Polymax Polycarbonate (best), and carbon-fiber/nylon composite (ultimate). The polycarbonate is lighter and stingier than the smoothed ASA which is quite thuddy.

Purrsephone (calico), Cpt. James T. Furk (orange & white), and Furlock Holmes (gray & white) would appreciate it very much if you bought some Evil-Engineering.com impact toys to help fund their Churu habits. 😁

This “finger flogger” is *super* fun to use. And it feels so *deliciously* stingy and nettle-y on the receiving end. But it breaks skin *fast* and is not for the meek. It’s currently not for sale for that reason. But I would love to know what you all think about it.

0154

Evil Engineering @evil-engineering.bsky.social · 29/08/2026

Many of our toys are UV (black light) reactive.

Meet Hermes. A very special impact toy, designed for fast hard slaps. It makes a CRACK like you may have never heard, it's tremendously comfortable and utterly unique. The handle is a lightweight aerospace polymer you won't find anyone else using. Currently available as a custom order via DM.

Evil Engineering @evil-engineering.bsky.social · 25/08/2026

“Be not afraid”. One of our more unusual creations, Ophanim is named after the angel described as “wheels within wheels”. Still in testing, this paddle delivers sharp sting on the flat side and deep tissue thud on the round side. Both sides make a unique popping noise. What do you think?

Evil Engineering @evil-engineering.bsky.social · 25/08/2026

‘The Belt’ is a sister toy to our “Teacher’s ruler”. Same gorgeous ergonomic handle, but with a flexible rubber-like blade. It’s incredibly stingy and can go from sensual to excruciating with the flick of the wrist. It’s been a huge favorite of our product testers and is ready for launch this week!

Special Custom Color order ready to ship out. Shown: a Sorceress crop in Teal, a Schoolmistress cane in Hot Pink, a 3/4 Kelleynator hammer and Initiate paddle in ‘Coral Wave’ which is a combination of the Teal and Hot Pink. The pictures don’t really do the Initiate proper justice. All hand finished.

Some creations are too evil. This bramble rod prototype has two settings on a scale of 1-10: 15 and 25. So it’s back to the drawing board for something a little less… lacerate-y. I am aiming for a toy in the 7-10 zone that hopefully still looks as wicked as this one.

Evil Engineering @evil-engineering.bsky.social · 22/07/2026

Three new prototypes in early testing/development. A sleeker, longer 2.0 version of our Hephaestus hammer, a super versatile all-new hammer design and a very unusual looking but massively ergonomic and thuddy paddle. Which one appeals to you?

022

Evil Engineering @evil-engineering.bsky.social · 21/07/2026

A lot of impact bottoms love *thud* but it can be a difficult sensation to deliver with accuracy and consistency. Foam wrapped pipes and chains, knotted rope and rubber balls are creative, but they aren’t engineered solutions. We craft precision tools to pit the thud exactly where you want it.

Frosted white or “bone” white? Which do you prefer? “Bone” is a new color of high-impact ASA we are in the process of adding to the catalog. What do you think?

Evil Engineering @evil-engineering.bsky.social · 20/07/2026

Small but extremely mighty! This 1/2-size “Kelleynator” hammer is designed to produce punishing deep tissue THUD for minimal effort. Made from three different aerospace grade polymers for three different jobs, the head, handle and pommel all work to produce comfort, balance and strength. #thuddy

We’re using a new material for some of our impact toys. Lyten PA1205 is a graphene reinforced nylon compound designed for use in F1 racing, long distance drones and other applications in aerospace and defense. It is one of the strongest polymers available anywhere. We use it for whips and chains. 😁

A little while ago, I made a plexi crystal dragon for Mistress just for fun. She asked me if I could make one that She could hit me with. This prototype creation is the result of that request. I call it TailStrike.
