yeah, personally the iron mistress shape just makes me go 'ghhughhh', and thats before i get into the whole 'hollywood screwing up history for the rest of us' thing, but the customer wants it for his dad who fell in love with the knife in the Alan Ladd film. i've tried to refine the lines somewhat to make it a bit less fugly, but we'll see...
I'm thinking if you put the iron mistress blade with the coffin handle you'll have a winner. I really like the Bell but I suspect it will have to wait, unless you can talk the customer into it instead...
my client had originally contacted Joe Yeates, but apparently he said he was no longer taking comissions for the sake of his health and a full schedule, but his iron mistresses are the nicest ive seen.
Self-hardening calcium phosphate cements present ideal bone tissue substitutes from the standpoints of bioactivity and biocompatibility, yet they suffer from (a) weak mechanical properties, (b) negligible osteoinduction without the use of exogenous growth factors, and (c) a lack of intrinsic antibacterial activity. Here we attempt to improve on these deficiencies by studying the properties of self-setting Fe-doped bone-integrative cements containing two different concentrations of the dopant: 0.49 and 1.09 wt% Fe. The hardening process, which involved the transformation of Fe-doped β-tricalcium phosphate (Fe-TCP) to nanocrystalline brushite, was investigated in situ by continuously monitoring the cements using the Energy Dispersive X-Ray Diffraction technique. The setting time was 20 min and the hardening time 2 h, but it took 50 h for the cement to completely stabilize compositionally and mechanically. Still, compared to other similar systems, the phase transformation during hardening was relatively fast and it also followed a relatively simple reaction path, virtually free of complex intermediates and noisy background. Mössbauer spectrometry demonstrated that 57Fe atoms in Fe-TCP were located in two non-equivalent crystallographic sites and distributed over positions with a strong crystal distortion. The pronounced presence of ultrafine crystals in the final, brushite phase contributed to the reduction of the porosity and thereby to the enhancement of the mechanical properties. The compressive strength of the hardened TCP cements increased by more than twofold when Fe was added as a dopant, i.e., from 11.5 0.5 to 24.5 2.0 MPa. The amount of iron released from the cements in physiological media steadied after 10 days and was by an order of magnitude lower than the clinical threshold that triggers the toxic response. The cements exhibited osteoinductive activity, as observed from the elevated levels of expression of genes encoding for osteocalcin and Runx2 in both undifferentiated and differentiated MC3T3-E1 cells challenged with the cements. The osteoinductive effect was inversely proportional to the content of Fe ions in the cements, indicating that an excessive amount of iron can have a detrimental effect on the induction of bone growth by osteoblasts in contact with the cement. In contrast, the antibacterial activity of the cement in the agar assay increased against all four bacterial species analysed (E. coli, S. enteritidis, P. aeruginosa, S. aureus) in direct proportion with the concentration of Fe ions in it, indicating their key effect on the promotion of the antibacterial effect in this material. This effect was less pronounced in broth assays. Experiments involving co-incubation of cements with cells in an alternate magnetic radiofrequency field for 30 min demonstrated a good potential for the use of these magnetic cements in hyperthermia cancer therapies. Specifically, the population of human glioblastoma cells decreased six-fold at the 24 h time point following the end of the magnetic field treatment, while the population of the bone cancer cells dropped approximately twofold. The analysis of the MC3T3-E1 cell/cement interaction reiterated the effects of iron in the cement on the bone growth marker expression by showing signs of adverse effects on the cell morphology and proliferation only for the cement containing the higher concentration of Fe ions (1.09 wt%). Biological testing concluded that the effects of iron are beneficial from the perspective of a magnetic hyperthermia therapy and antibacterial prophylaxis, but its concentration in the material must be carefully optimized to avoid the adverse effects induced above a certain level of iron concentrations.

The Wa-kamisori, Japanese straight razor, is a perfect example of the Japanese aesthetic. This razor was produced in the workshop of bladesmith Shigeyoshi Iwasaki (b. 1933), in cooperation with his apprentice Ryoichi Mizuochi. Shigeyoshi-san is the son of renowned metallurgist and sword researcher, Hiroshi Iwasaki, who is well respected as a leading authority on traditional forging techniques. Shigeyoshi Iwasaki is considered by many to be the greatest straight razor maker of all time. His work is quite simply beyond compare.
Made of the finest carbon steel and fire-forged with Rentetsu iron (wrought iron), the blade is polished with natural sharpening stones. The blade bear's Iwasake's mark on the back of the blade.
These razors are a source of great pleasure for collectors and users alike. Delivered in a beautiful kiri-wood case.
The 46 artisans and their works selected for this book are the most representative of the last 30 years. Each has their own style and character, mixed with utility and the knifemaking tradition of their home country and culture. Others are quite startling in their inventiveness: a simple steel knife with a handle made from a fox's lower jaw (Mickaël Moing, France); damascus steel blade and an ancient mammoth ivory handle (Pekka Tuominen, Finland); stainless steel blade with an ironwood handle encrusted with mother of pearl and precious stones (Harumi Hirayama, Japan); and a "button lock" knife of damascus steel, with a handle of damascus, gold, titanium and mother of pearl (Michael Walker, USA).
Fiore says: Here begin the guards of the sword in two hands. There are 12 guards. The first is the whole iron gate, that stands in great strength. And she is good to await every manual weapon, long and short, and for which it has a good sword, that is not too long. And she passes with a cover and goes to the close. She exchanges the thrust and places her own. She also beats the thrusts to the ground and always goes with a pass to the close and against all blows she makes a cover. And standing in this guard, one may easily make defense against anyone who bothers him.
Fiore says: This is the window guard, that is always quick with malice and deceit. And she is mistress of covers and strikes. And she argues with all the guards, both high and low. And she often goes from one guard to another to deceive the companion. She places great thrusts and knows to break and exchange, these plays she can do well.
Technical: you can strike strongly from here, and you can do the breaking of the thrust from here. There is no mention of the exchange: cross reference with the text regarding middle iron door with the spear (page 39r) suggests why: Fiore says: "...these guards on the right side cover and with the cover pass and place the thrust. And the guards on the left side cover and beat aside and strike with a blow, and cannot place the point so well." This is true whenever the opponent strikes from their right side (e.g. from whole iron door or woman on the right): as the strike comes in towards the defender's left side, they have to beat it all the way across to their right if their defence is starting on their left.You can also enter into close play easily from here after the cover (because you can't so easily keep the point in presence during your defence, and instead beat the incoming sword aside, there is a moment when both swords are off to the side, and so closing in is both easy and tactically sound).
Fiore says: This is the middle iron door, because she stands in the middle and is a strong guard but she wants a long sword. She throws strong thrusts and beats swords upwards with force and returns with a fendente to the head or the arms and returns to her guard. However she came to be called "door" because she is strong and a strong guard [is one which] is bad to break without danger and come to the close.
Tactical: this guard can go tasting the guards, and may be used deceptively (cf. posta longa). The point is in the centre line, but out of presence, so it can oppose the three guards that stand in the point, which are named as middle iron door, short guard and long guard on page 22r. It makes very strong thrusts, and because it is stable across the flat, and unstable in the plane of the edges, it is excellent for deception. The thrust can be made very quickly from for example woman's guard, and can either force through the parry, or slip it.
Tactical: the text here tells you that this version of cenghiaro works the same as the previous version. It is probably added here to make up the cardinal number of twelve guards. It does not appear in the Pisani-Dossi, which repeats fenestra (but on the left, which in the Getty is only mentioned on page 31, and shown with the pollax on page 36r). Here though it is mentioned that the rising blow from this guard can be aimed at the sword, as a cover, where in the previous version, the only targets mentioned are the head, arms and hands. So, you may parry from here (much as from the middle iron door). Given that the measure must be quite long for you to be safely in this guard, it is not surprising that the hands are the principle target ("always destroys the hands, sometimes the head and the arms").
