A compact modern rendering of the classic Yawara & Kubotan Style Self Defense Palm Sticks, with an ergonomic & firm Fist-Lock™ grip incorporated into the Patent Pending design!
Offered is ONE Patent Pending, Easy-Carry, Compact, Ergonomic Firm Grip, Self Defense Yawara Stick!
Offered in a Fatter 1/2" diameter rod than my previous Polymer sticks, and NOW made with Dupont™ Delrin® Grade 150 Homopolymer Acetal Resin,...in either Black OR White Rod and vailable in THREE length options! (6", 5-1/2", or 5" available, and 6" shown in photos)
An extremely tough and stiff polymer, that works really well in this application. The video below was a challenge I made to a Youtube Martial Arts guy (wmpyr), to actually TRY to break it by repeated hard striking, and from all angles into an old hardened truck tire. Just 4 minutes, and worth a few chuckles also:

I decided to make some of these in White Delrin rod because I noticed a LOT of women were buying my Polymer sticks, and in most cases they were carrying the stick in their Purses. As is NO surprise, women can really cram a LOT of items into those purses, ....and the "all black" self defense stick can get lost and not stand out within a large purse. These WHITE rod two-tone sticks will be much easier to locate them if needed. When seconds count this CAN make a huge difference! The 6" is the best all around pocket carry stick, as the longer length allows wrist and arm locking maneuvers a little better.
The 5-1/2" or 5" versions makes a nice dress shirt pocket carry stick, where it appears more like a Magic Marker than a Self Defense Tool.
The 5" versions make spinning in one hand easier, which is a FUN way to kill some time when needed, and get a hand dexterity workout at the same time. (a NEW spin on Fidget Spinners!).
For Pants or Jacket Pocket Carry ANY of the stick lengths nestles in most any pocket unnoticed and strike hard!
Designed & Hand Crafted in the USA!
Also, NO metal is used in it's construction, so these sticks can often be carried where a metal one cannot.
A thoughtful and affordable Gift, this is my 2nd "most affordable" hand made Yawara Stick for those on a really tight budget. For just a few extra dollars, you gain the benefits of a fatter and higher profile central Fist-Lock™ Grip with a wider striking surface. The wider tip surface also makes this a stick useful Acupressure Tool, Medicinal Pill Crusher, and Portable Door Knocker for Home Delivery Professionals.
I spend the same time on these as on my Titanium versions, and frankly it's not a great money maker for me for the time spent. (at least 1/2 hour to hand make and finish,...check out the tip and grip finishing photos) A bargain at TWICE the price! :-)
However, I wanted to make something that will still help keep my customers on a really tight budget safer, and hope that once they have a chance to handle this stick they might very well move up to one or more of my Titanium versions when they're in a better financial position. :-) Your Outer Fingers "Mechanically Lock" & Center The Stick Laterally In the Hand - Inner Fingers Add Substantial Grip...Creating Fist-Lock™! The raised reinforced grip fits into that "small pocket" created where your fingers meet the hand once the fingers are curled, as happens naturally when you make a fist.
The next to last photo shows the hand with fingers outstretched, and there is no "cup" presented in the hand. The LAST photo shows the small pocket created once the fingers are bent. Much like a Key Way holding a wheel onto an electric motor shaft, this grip design forms a "mechanical connection" of the stick to your hand! It has been well received by knowledgeable Martial Arts practitioners and MANY others as creating an outstanding grip! The GRIP Is Absolutely Awesome In that "Cupped Pocket" where your Fingers meet the Hand! Simple, comfortable, and EFFECTIVE!
Stay Safe!
NOTE: "Dupont™ Delrin® Series 100 Acetal Homopolymer Resin" is a long name, but a material this good for a defensive palm stick needs to be fully and accurately Identified because there are other formulations of Dupont™ Delrin® available with differing properties.
Also, this material is used by other manufacturers as a raw ingredient, and the actual rod I've made these from was manufactured by a company called "Ensinger" using the Dupont™ Delrin® 100 Series material outlined with the designation "Delrin* 150" originally marked on the rod. For you hobbiests types,....if "stiff" and "tough" are what you need, Grade 150 Dupont Delrin® is what you want! :-)

Delrin® 100 Series Properties and Performance
Mechanical Properties Performance
The resins in the Delrin® 100 acetal homopolymer series are distinguished by their high molecular weight relative to other acetal grades. This identifying feature of these high performance acetal homopolymers, along with their natural high crystallinity, yields materials that have:
Toughness, high impact strength, high resistance to repeated impact, and high elongation without the need for impact modifiers.
High mechanical strength and rigidity, without the need for fillers/reinforcements or other modifications.
Outstanding creep resistance and long-term fatigue endurance.
