The conclusion of Kale Stemmer

If anyone has read all three posts of the Kale Stemmer process they probably could have imagined the inevitable outcome with relative accuracy.  The short answer is, someone beat me to it.

Apparently if you drag your feet, lack focus and discipline; someone not only beats you to market with your idea, but makes a much better version of it.  I guess it’s only fitting my mother found it at a Bed, Bath and Beyond gave it to me as a stocking stuffer last year.  I can only suppose this was an attempt at humor.  (I kid, I love and appreciate my mother very much.)

I give you, the Looseleaf:

The design is on point: slick, easy, straight forward.  You could easily have this 3D printed.  I’m sure it costs pennies to make.  A quick search on Amazon revealed that this piece of plastic retails for $7.95. Certainly enough to go around to make Chef’n and the inventor quite happy.  Or whatever arrangement was worked out.

I hope whomever’s idea the Looseleaf was, it made them a nice chunk of change.  I will say, however, the “Stem-sational” was the superior name.

Kale Stemmer Phase 2: Successive Iterating

We left off last week at my first hurdle I needed to overcome, which left me dead in the water.  It wasn’t until I spoke with a friend who suggested 3D printing, which would fling the door open on the iteration process.  I knew about 3D printing but had written it off because I didn’t want a plastic tool.  But that was the problem.  I was getting stumped on the material!  My friend told me it doesn’t matter what the material is when iterating, especially since it’ll save me money to print several versions in plastic.

The next task was to figure out a 3D program I could use to mock the tool up.  I first looked to Autodesk because it’s the most well known.  They had two free options, TinkerCad and 123D.  I started with TinkerCad, which is probably the most approachable of the two.  After a few hours piddling around, I was satisfied with my first mock up.  I uploaded it to Shapeways and a couple weeks later, like magic, I get a physical thing in the mail!

The first lesson I learned was about size.  I knew when I saved it, I didn’t really have a good feel for how big it was going to be; and sure enough when it arrived, it was rather small.  Manipulating three dimensional objects has always come second nature to me.  I’m a kinesthetic learner, and can master quickly anything I need to use my hands to learn.  So I was surprised when it took me a while to really get my bearings with 3D software.  I think the difference is: even though the object I’m creating will ultimately be 3D, I’m working and perceiving it in a two dimensional way.  But I guess calculating in the learning curve is all part of the iterating process.

The second lesson I learned right away was about material.  I decided to print it in stainless steel because that was one of the materials Shapeways had available, and I figured, why not?  Since it was ultimately what I wanted the tool to be made in, and I just wasted a month banging my head against a wall about it.  I’m glad I did, because I learned that it wasn’t a good option to print in stainless steel as it’s 1) expensive and 2) has major printing constraints: I was not able to make the arms thin enough to really be pliable.

Lastly, the shape did not allow enough room for the arms to be manipulated around a stem.  Back to the drawing board I went.

I decided to mock up the next version using 123D, just to try out that software.  It took me even longer to figure out how to use that, and I did not do as good a job as with the TinkerCad.  It’s also pretty powerful software, probably too much for my poor, first generation 11” Macbook Air to handle.  However, I did have an idea for how big the tool was going to be this time.  The shape changed in order to make the tool work the way I had envisioned.

I made the arms on this model as thin as Shapeways would allow me to print.  This time I printed it in a few different materials, just to see what the difference would be.  I tried stainless steel once more because I like wasting money.  As it turns out, it was still too stiff to really be pliable.  I also printed it in a soft plastic, which was far too soft; and a hard plastic, which was juuust right.

I was pretty happy with the shape and size of the hard plastic version and having a hard time thinking how to make it better.  It was a simple design, it worked the way I wanted it to.  I showed it to friends and no one had any real feedback except, what else does it do?

Which made me think, what else should it do?  What if it could do more?  I know the whole point of the tool was to be a simple one-function kitchen tool, but if it had more than one function, wouldn’t it then be more valuable?

Maybe it was because I was reading 1984 at the time, but I like to call this next phase “overthink”.

My First Stab at the Kale Stemmer

Last year I decided to put what little money I had where my mouth is and try to actually make one of my crazy ideas a reality.  In the next three posts I describe the trials and tribulations of my first product creation attempt, and how the Kale Stemmer never came to be.  Or at least, not yet.

My favorite breakfast–and by favorite I mean I’ve cooked this for myself five days out of the week for the last year–is eggs and greens.  I sauté some onions and peppers, fry an egg on top, and then steam kale/chard/collards/spinach on top of that.  It’s delicious and nutritious, so when I’m a fatty the rest of the day, I can trick myself into feeling good about my eating habits.  The point of all of this is, I eat a lot of kale.

Kale, for those of you familiar with the leafy vegetable, has an almost inedible woody stem growing right up the middle.  It doesn’t taste very good and makes you fart all day if you eat it.  Most people get around this by using chopped up Tuscan or Dino kale, which has the most digestibly negotiable stem.  I’m OCD about it, so I end up spending a half hour slicing the stem out of every single leaf of kale before I chop it up.

My desire to make this process less of a time suck is how I decided to invent the kale stemmer!  Supporting arguments being: it was the most approachable idea to create, i.e. it didn’t require crazy engineering skills I couldn’t wrap my brain around; and more importantly, it’s a silly kitchen tool that only does one thing.  What do American’s like buying more than silly kitchen tools that only do one thing?  How many stores devote entire sections to silly, one-function tools?  And with kale’s popularity on the rise, I was potentially sitting on a goldmine.

Having finally decided on what I wanted to create, now I had to go about actually doing it.  Which proved a little daunting only because I had no idea what I was doing.  I started with what I knew how to do, which was to physically mock something up with similar materials available to me.  I headed over to SCRAP (Scrounger’s Center for Reusable Art Parts), one of my favorite resources in all of SF.  If you do not know of this place, you need to check it out!  It’s hidden away in the industrial triangle part of the Bayview, but you will not be sorry when you finally find it.  After digging around for an hour I found what I figured would do the trick.  By the end of the day, I came up with this:

Kale Stemmer version 1
Kale Stemmer, version 1

You can see from my very first mock up, that I possess the crafting skills of a second grader.  You can also get an idea for the form I was going for.  Two knife blades that can be manipulated like tweezers to adjust to the width of the stem.  In this case I glued two razor blades onto a metal frame and covered it with leather to make it look “nice”.  The problem with this model is I was looking for a metal that would be pliable in order to manipulate it to the shape I desired.  However, what I should have looked for is a firmer material with more shape memory, since this one does not spring back to it’s original shape.  The goal was for the tool to work like tweezers, where you squeeze the blades together and follow the shape of the stem.  That way you can cut out all types of stem shapes and sizes.

After completing my first mock up, I stared at it for about a week.  Now I had a visual for when I explained what my idea was to people, but it wasn’t exactly something I was proud of.  I knew I had to make it more professional looking.  My problem was I kept thinking that it had to be stainless steel, since that was the material I ultimately wanted it to be made out of.  I sunk hours of research into the properties of the material, how I could get my hands on it, how to work with it.  I made a trip to the Crucible to speak with a craftsman there about how to mock up my tool, which ended up being even more daunting since he went on and on about crafting a fine, chef’s quality knife–which was not what I was looking for at all.  I needed it to be simple and cheap, something that could be machine made.

Progress sputtered to a standstill: I had come to my first road block.  I couldn’t get past this barrier because I didn’t know how to manipulate stainless steel and I didn’t have the money to pay somebody who could.  Luckily I have a friend who is going through the same process with his own inventions, so I set up a meeting and picked his brain.  He told me not to get hung up on the manufacturing process before I even have a tool to create.

How could I have been so dense?  How many countless articles had I read about “attacking a problem from all angles” and “pivoting” and all of those other Google keyword catch phrases entrepreneurs love to throw around.  And yet here I was, stuck on my first problem, and my solution was to continue to bang my head on the wall when really, I only had to walk around to the other side and open the door.

Thankfully I did one thing right in talking with my friend.  He was able to turn my problem around for me.  Now that I had found the door, I could walk through and start the next phase: successive iterating.
