Quoted: this entry tool looks like its full of win. fubar

Yes, yes it does.

I saw go with one of these that we use in the fire department. Beat the crap out of a halligan tool because it combines about everything you would carry into one.

Quoted: Quoted: You never know. You might have to pry something out of a MRI scanner someday... ...when the power switch is jammed in the 'on' position...and the electricity can't be cut....

You don't really turn the magnet on and off, you turn the radio frequency on and off.  The magnet is superconducting...it just keeps going and going, unless you heat it up by letting out the helium.  Then all hell breaks loose, and you'll be days without a functioning MRI while you wait for helium, re-cool the magnet, and then ramp up the magnetic field.

So it is much more economical to just winch whatever is in there out of the magnet.  Just don't let the winch get pulled in...

Quoted: Quoted: I used to work in the medical equipment repair field and we had a variety of hand tools made out of titanium to work on or around MRI machines.  This is because it is non-magnetic. Unless you are in a similarly specialized situation it would be a complete waste of your money. How do you piss off an NMR (MRI) tech?  Throw a handfull of staples at his instrument!

Oh, DAMN.

I'm sending that one on to a couple of nuke physicists I know...

Holy crap.

He must be the most useful guy in the shop, now that he's grown two extra arms.


The warnings about beryllium are many and frightening.  Thou Shalt Not finely divide it!

   BERYLLIUM

   Toxbase summary

   Type of product

   Used in nuclear reactors, electrical insulators and resistors, spark
   plugs, microwave tubes, the aerospace industry, photographic equipment
   and many tools.

   Toxicity

   The lung is the main target organ of beryllium toxicity.

   Beryllium lung disease is classified as acute or chronic dependant on
   the duration of disease rather than the duration of exposure. The
   acute illness does not persist beyond one year.

   Chronic beryllium disease is a cell-mediated (delayed)
   hypersensitivity reaction characterized by granuloma formation and
   pulmonary fibrosis which may be fatal.

   Features

   Topical

        -    Beryllium compounds may cause contact dermatitis.
        -    Beryllium ulcers occur where a beryllium crystal penetrates
             the skin at a site of previous trauma.
        -    Beryllium chloride, fluoride, nitrate or sulphate are acute
             eye irritants.

   Ingestion

        -    Gastrointestinal beryllium absorption is poor and systemic
             toxicity via this route does not occur.

   Inhalation

   Mild inhalation:
        -    Metallic taste, cough, breathlessness.

   Substantial inhalation:
        -    Cough, chest pain, metallic taste, exertional
             breathlessness, nasopharyngitis, tracheobronchitis,
             conjunctivitis, pneumonitis, epistaxis and fever.
        -    Additional features seen in chronic beryllium disease
             include fever, anorexia, arthralgia, nausea, vomiting,
             haemoptysis, palpitation, convulsions, renal calculi,
             corneal calcification, hepatosplenomegaly (secondary to cor
             pulmonale) and systemic granulomas causing lymphadenopathy
             and parotid gland enlargement.

        -    Chest X-ray may show upper zone nodules and fibrosis and
             there may be a restrictive ventilatory defect.

   Management

   Topical

        -    Skin nodules from subcutaneous implantation of beryllium
             metal or its salts are best managed by local excision.

   Ingestion

   -    Beryllium salt ingestion is not a significant toxicological
        problem.
   1.   Management is entirely supportive.
   2.   Gastrointestinal decontamination is not necessary.

   Inhalation

   -    Most cases are occupational.
   1.   Occupational hygiene is paramount.
   2.   If pulmonary toxicity is suspected remove from exposure.
   3.   Symptoms of acute and chronic beryllium disease respond well to
        oral steroids.
   4.   Experimental studies to assess the value of chelators in
        beryllium poisoning are underway, but there are insufficient data
        currently to recommend their use in man.Urine beryllium
        concentrations allow assessment of beryllium absorption but
        chronic beryllium disease is not excluded by a low urine
        beryllium concentration.

Edit: I was so far off from whati just posted thati couldnt even leave it up to flame. Beryllium is also used in x-ray windows to filter out visible light.

Ok, i was close but too embarassed to leave it up after i found out i completly mispronounced that word.

While the Denver's a great tool, there's no substitute for Brannigan's favorite implement. Total WIN? A Denver and a Halligan.

Ill second taking both. Only my slack man better have one and not stick me with a nozzle and both of them. That TNT Tool has come in handy quite a few times. If i could only take one of them though...TNT would be taken by me more often than a halligan.

Halligan is quite a few times cheaper from what ive seen though.

Quoted: Quoted: We had a jackass put  beryllium axe on a grinding wheel once. Wasn't sharp enough for him. This guy is only a bit bigger of a jackass than the guy who designed and buikt a beryllium AXE in the first place.

At the time Army EOD had tool kits for non-mag and non-sparking applications. One tool kit had an axe that was to be used for some specific EOD procedures. This was in the 80's when titanium was in short supply and Beryllium was considered ok as long as you didn't machine it. Not sure whatever happened to the guy long-term, but we yelled at him to stop before he generated "too much" dust.

Then again he's probably the SGM at 52nd group by now.

Bump! Cuz when Obama takes our gunz we can fall back on thez!

Saw one one of these in HD last night.   This screams to be tested on Zombies.

Hmm...
Titanium...
Capable of wreaking just about anything...

Sounds like what you really need is a FLYING Crowbar.

Gordon would be proud.

While the ultimate tensile strength of some titanium alloys is similar to some steel alloys, its modulus of elasticity is MUCH lower.  That is the constant that tells you how much it will deflect / bend / deform under stress.  Guess what you're doing when you're working with pry bar?  Yep, applying a bending stress to that pry bar.  Guess what it's going to do?  Yep, bend a lot more than a steel bar with the same dimensions.

Unless you have to carry around a pry bar in your back pocket all day, steel is better.

Yep, about HALF that of steel.  Meaning that crowbar has to be LARGER in diameter and the sharp prying ends are more likely to bend, or break.

Strength, ductility, modulus and weight are all factors.  Grow some muscles.

isnt chromoly lighter than titanium, just not as strong, even though chromoly is stonger and lighter than steel? not sure and wondering

Not even.  Chrome-moly alloys ARE STEEL.  Same modulus (stiffness), just higher yield point (where it starts to bend) and higher ultimate tensile strength (how far it will bend before breaking).

There isn't any significant difference in stiffness or density between low carbon steel and 4350. But the 4350 steel can be quenched and ttempered, making the yield and ultimate strength much higher.  A crowbar won't be any stiffer.

If a pair of bridges were made, one of low carbon and the other of chrome moly steels and were made with EQUAL STRENGTH, that means each one was stressed to the same percentage of its respective yield point, the chrome moly bridge would be lighter AND MORE FLEXIBLE.  Or in other words, the low carbon bridge would flex less under the same load.

Odd, isn't it?
