Upgrade your K1 or K1 Max to the latest anti-clogging technology, or replace your K1C hotend with this premium Upgraded K1 Series Hotend Kit. Featuring an integrated bimetallic "Unicorn" nozzle, this aftermarket hotend is engineered to solve the most common K1 extrusion issues while delivering extreme speeds and high-temperature reliability.
🚨 CRITICAL: Check Your Connector Before Buying
Creality updated the toolhead circuit boards over time. You must check your specific machine before ordering to ensure the plugs fit. We know it adds a step, but checking now saves you from a frustrating return later!
How to check in 3 easy steps:
- Turn off your printer and remove the plastic front fan cover.
- Look at the small circuit board (Toolhead PCB) where the hotend cables plug in.
-
Choose your variant:
- 👉 Terminal WITHOUT Buckle: The plugs are completely smooth and slide in without a clip (Typical for older K1 / K1 Max models).
- 👉 Terminal WITH Buckle: The plugs have a small plastic latch/snap that locks them into place (Typical for K1C and newer K1 / K1 Max models).
Why Upgrade to the "Unicorn" Design?
- Zero Leakage (All-Metal Integrated Design): The heat break and nozzle are crafted as one solid piece. This eliminates the gap where filament usually leaks inside the heating block, and allows for easy, one-handed cold nozzle swaps.
- Banish Heat Creep: The titanium alloy throat drastically reduces upward heat transfer, keeping your cold zone cool and preventing jams. (Tip: For enclosed K1s, open the top/door when printing low-temp filaments like PLA!)
- 600mm/s High-Flow Performance: The enlarged nozzle chamber increases the melt zone by 30%. With a massive max flow rate of 32 mm³/s and a burr-free orifice, you get perfectly smooth extrusion at top speeds.
- Ultra-Fast 360° Heating: The rugged 60W encircling ceramic heater melts plastic uniformly and reaches 200°C in under 40 seconds.
- High-Temperature Durability (300°C): Crafted from copper alloy and hardened steel, this nozzle easily handles abrasive and engineering-grade filaments like Carbon Fiber (PA-CF, PLA-CF), PC, ABS, and TPU.

Very nice knives for the price, with additional options in the same pattern!
Size: Steel King 15Pcs 10.4"×7"×15.4"
It’s been 10 months, so I feel like I can finally give a decent opinion on this knife set. First of all, I really appreciate how sharp they are out of the box. The set of different blade shapes suits my needs quite well, with the exception of the bread knife, which I swapped in the block for Brodark’s deboning knife. I also added their breaking butcher knife, cleaver, and brisket slicer to my collection, all which match the handle style for this set. (I really liked that I could get the same pattern for some additional blades to expand my kitchen set without getting a different pattern.)
The knives should never go through the dishwasher - I tested with one of the steak knives and water spots rusted lightly. I was able to buff the stains out, but the “high carbon stainless steel” is definitely as described. When used normally I do soap and water cleanup, dry, then back in the block without issues. I have honed the chef and slicing knives so they glide through food more easily, but they retain their edges well enough I haven’t needed to repeat the process in normal use.
The block is quite heavy and very durable, but still has a rather compact space use as it stands pretty close to vertical. I have mine pulled forward on the counter as our cabinets are rather low, and there is no hint of instability when drawing or resheathing blades. The finish is quite nice, and no need for touchups or worry about the blades wearing in the slots like softer wood blocks can have happen. All the blades fit well in their respective slots. You do need to grip the handles by the ends to draw some of the blades as there are a lot of tools in close proximity, and my fingers and hands are large.
I got my set last Black Friday. With the prices and discounts that keep popping up, you could still get a pretty good price most of the year. If you want the option for additional knives of similar handle pattern, do a quick Amazon search for ‘Brodark knife’ and check their options. There have been a lot of good spot sales lately!

Very nice knife set.
Size: Steel King 15Pcs 10.4"×7"×15.4", Size: Steel King 15Pcs 10.4"×7"×15.4"
Got these as a Christmas present and they are a very nice set of knives. They are very sharp so be careful when taking them out of the little sleeves they come in. The wooden base is surprisingly heavy and does a great job at holding the knives without sliding around. The built in sharpener works good to fine tune the edge with just a gentle pull through the ceramic side. They also come with a lifetime warranty which is nice.

Great Knives
Size: 12-pc, Color: Gray
These are great knives.
Sharp as can be.
Be careful.
Wash delicately & don't put them down point first in dishwasher. Lay them down flat. The point is sharp and could bend or get bent. Point is sharp as hell and thin.
But very hardy strong knives

Better than what we were using.
Size: 7-pc, Color: Brown
I grew tired of going for a knife only to find that what we had were dull, pitted and bent tips. So I gathered them all up, sorted through them and threw the worst of the worst out. Discovered long ago that those expensive knife sharpeners don’t work either. So I purchased this set as a throwaway set. I’ll use them until they too have seen thier better days and then buy another set.
