Scientists made a wooden knife that's three times sharper than steel blades:

The gold standard for knives is usually steel or ceramics, but in a new study, appearing in the journal Matter on Oct. 20, material scientists describe their latest creation: A "hardened wood knife" around three times sharper than a stainless steel dinner knife. It can "easily" cut through a medium-well done steak, according to Teng Li, a materials scientist at the University of Maryland and first author on the paper, and can be used and reused many times.

[...] Li's team developed a two-step method for hardening the wood in their knives that increased the blade's hardness 23-fold. This was achieved by ensuring the wood retained a higher level of cellulose.

Typically, wood contains only about 50% cellulose, which provides some structural integrity, and weaker molecules make up the rest. Li's two-step process was able to remove these weaker components but retain the cellulose. Coating the wood in mineral oil helps protect its sharpness during use and washing.

[...] They discovered the two-step process the used(sic) prevented defects from creeping in. "The strength of a piece of material is very sensitive to the size and density of defects, like voids, channels, or pits," he said in a statement.

The team didn't stop at hardened wooden knives, either. They also developed wooden nails, showing they were as sharp as conventional steel nails.

    1.) What's the survival rate for COVID (minus co-morbidity factors/other medical issues present already in a person)?

    ANSWER = roughly 99++% across ALL age groups (or close to it)

    2.) GIVEN THAT FACT, then WHY TAKE AN UNPROVEN SHOT that's PROVEN it generates ALL THESE BAD CONDITIONS:

    pericarditis
    myocarditis
    NERVOUS "twitch" disorders (sp? gillian barre, huntington's disease like, etc.)
    PARALYSIS
    cancer
    sterility
    COVID RASH (huge blisters & "burnt" red skin that falls off etc.)
    brain aneurisms
    lung CLOTS

    (for the LAST 2? GET A D-DIMER TEST to help catch & stall BLOOD CLOTTING leading to them, catching it EARLY!)

    & more...

    ALL BASED ON FALSE POSITIVE RESULT GENERATING PCR TESTS per all the evidences I noted here on that note vs. your bs WHICH HELPED ME PROVE IT no less, lol https://soylentnews.org/comments.pl?noupdate=1&sid=45332&page=1&cid=1185265#commentwrap [soylentnews.org]

    *** IMPORTANT/ADDITIONAL FACT:

    PCR tests DO NOT TEST FOR ANYTHING BUT DNA (double-helix) & what do viruses contain? RNA (single-helix) ONLY!

    (To which the CDC got rid of OLD TESTS (that also did false positives due to cycling turned up too high to panic sheeple into taking a CLOT SHOT) & NOW "new tests" are out? No thanks!)

    ---

    PCR test cycles TURNED UP TOO HIGH in cycling per Kary Mullis the NOBEL LAUREATE who was awarded the NOBEL PRIZE for that test (nobody knows it better than he - HE INVENTED IT) DID OCCUR & the fact "new tests" ARE out PROVES IT - but those that took the shot based on FALSE POSITIVE RESULTS I list above ARE IN DEEP SHIT (dead).

    A DOCUMENTARY that further illustrates the BS of the PCR test?

    ( w/ FAUCI saying "anything over 33 cycles is not worth doing it higher" WHICH THEY DID DO, by testing way, Way, WAY over 33 cycles (so much so, things like a BANANA show "covid positive") to CHUMP YOU into taking the CLOTSHOT - period!)

    FACT!

    IN FACT (pun intended) GRAPHENE OXIDE's in Pfizer, Moderna, Johnson & Johnson (Janssen) + AstraZeneca:

    AND, Guess what is a MAJOR CAUSE of myocarditis, clotting etc.? That's right: GRAPHENE OXIDE, "surprise, Surprise, SURPRISE" (not).

    Vaccine makers don't KNOW WHAT THEY'RE DOING (or do & want to kill you)!

    * AND, moreso when a PFizer scientist ADMITS natural immunity is better than taking the CLOTSHOTS (NDA he signed got him scared for it too, admitting it)

    Then, the WHO changes the DEFINITION of "pandemic" from NUMBER OF DEATHS vs. NUMBER OF CASES (which "The Wayback Machine" still has evidence of) to make a herd stampede in panic (herd of stupid sheeple) due to false positives from a BOGUS "test" per above, that ROPED DOPES IN as said "panicked sheeple herd" to take a shot that f's you up!

    E.G. All you have to REALLY "endure" is a flu like condition pretty much - e.g. My Mom's 84++ & SURVIVED IT (beating it in 7 days)!

    * YOUR "CURE" IS WORSE THAN THE DISEASE!

    (The proof is that when your body after vaxing LOSES its IMMUNE SYSTEM (see cytokines below in my ps) & MORE PEOPLE WOULD DIE in FLU SEASON (just starting now 10/2021) & THEY ARE NOW "right on schedule" per https://www.brighteon.com/6b1d70d0-d79d-4cdf-9385-d0a7726c46a1 [brighteon.com] )

    In fact, due to VARIANTS being produced by the vaxxinated? I'd say the VAX IS THE DISEASE (as it debilitates your immune system to ZERO efficacy eventually & YOU DIE...)

    APK

    P.S.=> Why fix something that's NOT BROKEN (your innate native immune system) UNTIL the vax damages your "killer T" cells proven just above (specifically T1 marker type that marks infestors via cytokines for leukocytes envelop & digestion removal (or possibly lymphocytes doing so also)) - especially vs. something that DOES NOT KILL YOU in 99++% of cases minus ANY OTHER "co-morbidities"? Additionally given that - WHY THE "BIG PUSH" to PUSH (like drug dealers do & in this case, "LEGAL" drug dealers) to put a vax in you that does NOT WORK as advertised in the 1st place?? LOOKUP Franc Zalewski and see EXACTLY why here https://www.brighteon.com/0ff2ee6a-413a-4e4e-b516-831eb394bc90 [brighteon.com] Where he shows SOMEKIND OF ORGANISM self-assembling made of carbon & aluminum floating around in VACCINATED FOLKS' BLOOD doing WHO KNOWS WHAT!... apk
